This game is absolutely EXPLODING with content without having any grinding and has tones of replay value on top of that. Each campaign (there's 4) is excellent with each knight having their own distinct gameplay style and (with the exception of 1) all having completely unique level layouts. While it seems that Specter Knight is the obvious fanfavorite out of these (and I'm inclined to agree) ALL OF THEM are top quality and worth your while. On top of that there's the added little mini challenges and a whole ass platform fighter in here as well (though it is a bit simplistic). Aesthetically wonderful too, this pixel style really appeals to me and it's complimented by a great soundtrack. Play this game.

Much better than 2 but the level design I feel is worse than it is in Advance 1. The partner system, while cool and customizable, isn't a drastic game changer or anything like some people claim it is. Game just ends up being mediocre and somewhat bland. Don't bother going for the "true" ending.
Somewhat recommended if you enjoyed Advance 1 but that's it.

(Got to Night 4 and stopped because fuck that night)

This game attempts to tackle the problem the FNaF series faces with repetitive gameplay but doesn't do so in the most elegant way. All of the ideas it attempts to explore seem like they'd be cool as inbetween main gameplay minigames but... they are the main gameplay. They just aren't substantial and there's no sense of escalation as the game progresses. I hear the custom night is good though, if you care about that.

This game is objectively not good. Bad character balance, disgustingly simplistic gameplay that barely ever requires adaptation, and mediocre visuals all lead to this game not having much going for it.
That being said I absolutely adore this game, it's most definitely the nostalgia speaking but still.

The gameplay in this one departs from previous FNaF games, and I think it's a net positive. The lack of being able to see the animatronics on cameras I think adds to the fear factor as you don't get to see them in any capacity until they're close enough for it to be uncomfortable.
The gameplay in this one is also, I'd say, probably the least luck based out of the original 4. It turns into a quick decision making game about which of the 4 options you need to deal with first, left door, right door, bed, or the closet. The hearing in this one also really amps up the fear factor, the energy given off from staring out into your dark hallways having to listen for the sound of breathing is something not replicated in the series since.
FNaF 4 is I'd say the best FNaF game out of the original tetralogy, and I'd highly recommend anyone who's enjoyed one of the FNaF games to play this one if they have a pair of headphones.

This game is actually scarier than the first but it suffers from mechanical issues.
For the scare factor I think the emphasis on keeping track of one animatronic does wonders, as opposed to FNaF 1 or FNaF 2 where your role is passive (waiting for things to show up and dealing with them) here you have to actively be tracking down Springtrap and luring him as far away as possible. The consequences of this are as soon as you lose him for just a second (which is easy to do, he really blends into the cameras) panic mode is instantly initiated at full blast. This is made even WORSE by your systems failing, taking away your only lines of defense and the wait you have to sit through for them to fix is agonizingly tense.

Sadly, despite its horror factor, this game suffers from gameplay issues. Since Springtrap is the only animatronic if he doesn't act aggressive enough you pretty much instantly win, unlike in other games where even if one wasn't being aggressive the others would make up for it. The reverse of this is also true, since Springtrap is the only threat here he's more dangerous than the ones before in other games, so if he decides to be super aggressive then you're going to be having a bad time. Still though I don't think this game ever outright decides you lose like FNaF 2 does, so that's a plus. Most of the Phantoms barely ever show up, BB, Foxy, and Freddy are the only ones you'll consistently have to deal with which sucks since that's only half of them. Additionally one of the phantoms (Puppet) is so terrible that if you get caught by them your run is basically over. The way to get the true ending isn't intuitive at all and was designed 100% with internet guides in mind, I don't think that's very good design.

If you enjoyed any of the other FNaF games give this one a go, it's definitely one of the best FNaF has to offer and because of that is also a decent one to play if you just want to get into the series.

Game simply has too much going on at once, and there are moments where luck just decides you lose. The addition of the music box makes it so you will be spending your entire time looking at 2 screens, which while was also true for FNaF 1 at its hardest, its true here for the entire game. The mechanics of Foxy aren't explained well enough for how absolutely crucial they are to the game, which can really hamper anyone not already familiar with the game. Character designs are good at least.
I'd say play this if you want to gain a greater understanding of the series, but nothing more than that.

Pretty tense game that even at high level can be somewhat nerve wracking as opposed to later games where that sense is kind of lost just because of how much shit is happening at once, horror doesn't work if you have no time to breathe. Mechanics are somewhat exploitable but not to the point they break the game.

Well controlled and wonderfully designed 3D collectathon. Aesthetically excellent, both being adorable visually while also having a killer soundtrack. My biggest complaint with the game is probably that it just ends too quickly for how good what's there is, though the DLCs remedy this somewhat. Highly recommend the Death Wish DLC if you found a large portion of the game lacking difficulty wise like I did, it really does pack a punch.
If you ever enjoyed a 3D platformer or collectathon game, or those genres seem appealing to you, pick this up.

This game has NO business being as good as it is. Best pinball experience I've ever had, completing the dex is fun and rewarding. The two separate boards help with the game getting stale as well as giving it some level of pesronalization. The minigames are all fun, the biggest annoyance is Jirachi but you'll probably find it at least once if you're going to complete the dex before you finish everything else. Game also looks nice.
Recommended if you're a fan of pinball.

It's kind of impressive how bad they made this game considering its predecessor. This game legitimately does nothing that makes me enjoy it aside from letting me play with physics that are mostly the same from Advance 1. Levels are bad, bosses are bad, it really just has nothing going for it.

Yeah, this is the best Classic Megaman, no contest.
Levels are great, they each have distinct things unique to them that still keep the focus and gameplay the same. Only two I have any sort of problem with are Hornet Man and Jewel Man but with the ladder it's really only one jump and it's not like the entirety of HM's level is bad. Boss balancing is good here, there are some that are easier than others (Galaxy Man, Splash Woman) but none is an impossible first pick like some other games in the series, and no Wily Boss comes off as bs like ones only weak to one weapon or the abominable Yellow Devil Mk-II. I have consistently found use for EVERY ROBOT MASTER WEAPON which is actually huge, no other game even comes close to that.
Megaman 9 doesn't do anything new, but it takes all the good things Megaman has and uses them to great effect and the result is wonderful.

Nice, basic Sonic fun. This game doesn't do much to stand out but it does what it does well, the main new thing it has is the way it handles 2D playable Amy which I actually really like, she's my favorite character to play as here. Special stages are terrible though.

It's a fine racing game. I never bothered to unlock absolutely everything but from the stuff I did it was somewhat of a fun challenge, lack of stages really drags this game down along with character balance. The stages that are here though are actually pretty good, Radiant Emerald is probably the worst (and an obvious rainbow road wannabe) but is still fun enough.
