I'm surprised on how little this game differs for its predecessors, sure, you have a few new things like the power blows, but the core gameplay is basically the same, to the point that if you are a casual player, most of the changes would be imperceptible, this isn't necessary a bad thing, but doesn't give you a reason to play it if you have another DOA, outside of maybe a campaign, which isn't very deep (Specially because of the open ending) and all over the place, at least I can say is amusing. In short, is a fun game, but one with very few reasons to recommend

This is a very honest fighting game, every character has basically the same tools with unique characteristics, so with solid basics (Attack heights, counters, grabs, etc.) you can probably choose any character and win, but that also means that the skill ceiling is very high, a couple mistakes and you are out, so you really have to think to win, especially in team battle were your partner can heal if you switch, the result is a very engaging experience, one that doesn't surprise me to be so fondly remembered.
If you are here for the campaign, I have to warn you, the plot is a mess. Each fighter goes through 7 fights (6 + final boss) with some cutscenes between them, which may or may not be connected, the result is a barely coherent tale with some (Gen Fu for example) and a series of nonsense with others (I'm looking at you Ayane). Even the final boss is only relevant in like 3 of all the 12 fighters stories. The bright side is that each is like 10 minute long, so it isn't a lot of time and well, at least you can say it tries to make something more than the typical fighting game of the time.
Also yes, this game is full of fan service (Just look at the CG galley), be careful if that's a turn-off, otherwise, enjoy

So much wasted potential... when this game is adapting the manga/anime is fantastic, the animations, music, voice acting are great, even the gameplay is diverse and fun, but the second the mobile BS enter, everything falls apart. The tutorials are annoying, all the requirements to improve a character are clearly bloated to make money, outside the adaptation, the gameplay turns to a repetitive series of fights and fetch quests, the original story is too low profile and inconsequential to be interesting. Fuck, not even the gacha is well done, who the hell thought that a 0.6% chance for a good character is enticing?! Specially after banning people for doing reroll (I know they regret that, but the damage was done). Look, I would love to pay for a version of this game with only the manga/anime parts (And maybe the cinema minigame), but the sad truth is that this game is doomed to die in a few months, because is unable to gain gacha players with its greedy rates, and it can't maintain the OPM fans for the simple fact that this game isn't what most of them want.

Rez is a very deceiving game, for the aesthetic alone you can believe that is a relaxing and easy game, then you play it and learn how chaotic and intense it is, which can let to a lot of frustrations (Specially for the vague tutorials), but then you try again and is not so bad, specially because if you know what to do, there's a lot of "Threats" that you can simply ignore. So at the end of the day this game lives or dies for your patience/interest in the concept, and that's why I can understand this being a masterpiece to some, while being nothing more than a frustrating and pretentious experience to others. For me? It was fun, but I don't plan to play it again haha

You know this game is fun, even if you haven't played it yet, you know it is fast-paced, violent and light in plot. So just let me tell you a few things that surprise me, for better or for worst
First, the fact that full screen blocks you to that window (Unless you trick the program) is BS and makes the option of borderless completely useless. The fact that you can't skip logos at the start is annoying. And the position of the terminal button can make you press it in the heat of the battle (Which is a problem).
Second, for a game so focus in violence, it is really fun to explore for secrets, specially because the map always tell you where the things are, just not how to get them. The only problem are some levels that block back tracking without warning.
And finally, I'm surprised that I haven't heard as much praise for the progression, because it is excellent, in every level you feel like you are discovering, unlocking or trying something new, that being weapons, weapon mods, runes, powers, enemies, bosses, etc. There's always something exciting to do, and no every game can say that, so I think that deserved a bit more love.
A great game and a must-play if you like shooters

This is the perfect game to play on the go, because you can save anytime you want, the maps are easy to read and the plot don't usually interrupt the gameplay, also the level design has enough diversity to make it a consistent joy. Sadly, the history is quite generic and a bit confusing if you don't follow the path the game intended for you to take. I never expected a complex social/economic comment, but I mean, the objective of the villain is to conquer the world, you can't get much lower than that.
