I have a personal hatred for over-the-top gimmicks in video games and that's all this is. If you want to play a Mega Man game then you won't get that from this because you'll just be playing a snowboarding level or going through a stupid maze or doing a pointless puzzle or something.
1998
Brutally difficult and not in a way that feels fair. There's a masochistic side of me that enjoys it for that though, and the weapons are all really cool. If you play the game with Bass please do yourself a favor and let yourself play with the bosses' weaknesses because it takes a full minute to beat them at minimum otherwise.
2008
In my opinion, the best classic series game. The only problem is that the game design will deliberately to things to kill you when you don't know they're there rather than giving you any chance to react or deal with it, but even then I understand that because this was a "return to form" and most people think of Mega Man as the kind of game that did that. Level design is otherwise fantastic, the enemies are really fun, the boss fights are the best in the series, the music is great, and this is the best set of weapons the series has ever given us. The endless mode existing is just icing on the cake.

I don't think it's as good as Mega Man 9 but it's not big enough of a difference for me to care. It technically is even more polished but the level design is worse and a handful of the boss fights suck. They focused on making the weapons just fun to use instead of making them all practical and I think it worked out wonderfully. Also has an endless mode that you could argue is better than 9's.

Your more modern Mega Man game. The shop is especially broken in this one and it's a bit short but that's about it. The stages all were really fun and the bosses and minibosses were pretty good too for the most part. The Double Gear system is a great way to get people acquainted with the more difficult gameplay while also not being super intrusive for people who don't use it.
1995
Still solid but a step down from the first two. You take way too much damage from everything and the soundtrack is way too same-y and not very well-composed for the most part. It's fine enough though if you can get past the absurd amount of unnecessary collectibles there are.
1997
A lot of people would have this as their favorite X game, but I think it's a bit style over substance. The head upgrade is very broken but in the kind of way that makes the game better. It's really easy and I prefer the game feel of the SNES trilogy.
2000
Not only does Alia stop you from moving way too often, but the level design itself has way more stop-and-go mechanics that just do not suit this series at all. A lot of it feels really derivative from X4 too. This is the first X game I didn't 100% on my first playthrough.
2001
Playing this game makes me feel like I'm losing my mind.
2003
Very boring, but an attempt was at least made and it looks pretty without taking assets from its predecessors. There is no reason to play this game.
