For the love of god play the SNES version and play as Bass it makes the experience so much better. Honestly I like this one it's pretty good under those conditions, fun set of weapons and the levels are generally good when playing as Bass.

Not a fan of this one, probably my least or second least favourite classic game.
iirc, two of the levels are weird gimmicks that change the gameplay and of the other stages the only ones I'd call normal fun mega man levels are Grenade Man, Search Man, Sword Man and like Clown Man, Astro Man I guesss but I don't like those levels for their weird gimmicky stuff even if it doesn't change the gameplay too much. I do like Aqua Man's stage though.
The game is very nice looking but it has the same issue as 7 for me where the sprite size makes it feel weird to play and also the Wily stages SUCK

Eh not a huge fan of this one. The bigger sprite has always made it feel weird to play for me and while I do think the levels are great it's just not too memorable in my mind. Like it's great don't get me wrong but it doesn't stick with me much.

I am a weirdo and honestly believe this (or 4) is the best NES mega man game. First of all it's beautiful, they really knew exactly how to make NES games look fantastic by this point and it shows. The weapons are pretty good too, nothing too spectacular but there's some fun ones in there. The world wide travel theming is fun as well and I love how they started introducing hidden secrets in levels here.
The adaptors are fun too, this is the game I would recommend the most to new players to the series because the jet adaptor really helps ease you in to the experience. It's not the hardest game in the series or anything but I earnestly love it.

Eh it's alright but the definition of formulaic mega man game.
It's very easy (comparatively) and the weapons are mostly terrible, and you don't even need them since the charge shot it overpowered. I like most of the stages but they just don't stick with me very much.

THIS IS WHERE IT GETS GOOD
The first truly great mega man game, like all the levels are really well designed, this is the first game where a lot of the weapons are good instead of like 2 or 3, the music is great, it has a lot of levels due to two castles, visually it looks great too. Seriously if you tried playing 2 and didn't like it play this or 6 instead if you want to get into the classic mega man games.

The main 8 stages are generally good but hitboxes are bad like the entire game and the slowdown is unbearable, play on the legacy collection to fix that I beg of you
Doc robot stages SUCKKKKKKKK SO MUCH
You can really tell they rushed this one (eghehehehe get it they introduced rush in this one but they also rushed the development) Better than 2 though yeah I said it

Hot take I don't actually like mega man 2 very much yeah it defined the series but okay cool it's kindaaaaaaaa mediocre aside from that
The music rocks though

It's the first one it's kinda shitty but I like it sort of

Weird feelings on this one. This game was like the primary thing I wanted to play on switch because I loved Splatoon 1 and the trailers made it look so good and yeah as a kid I loved the hell out of this game but looking back on it there are some weird things about it.

First of all, the maps kind of suck overall? Like yeah there's probably more good ones in this compared to 3 right now but wow I do not like the stage design here very much. I haven't played it in a while but it always felt like the levels had weird layouts that were interesting but not much fun, like Albacore is a very interesting stage design wise but when you actually play it that map is terrible. There are some peak maps though The Reef is one of the best ever and I desperately want it back.

Another thing is the weapon kits. A lot of them are just bad. Like why was splashdown given to so many weapons that don't fit it for example. Also why was splashdown in general that special sucks ass. Also like 20 arbitrary weapons didn't get a third kit in this game which is even more disappointing now since looking at 3's update cycle third kits in general don't seem that likely in my eyes.

Now onto the worst part for real, the fucking special weapons. Okay so 1's special weapons were fun but like horribly balanced right so in 2 they shifted it so that the specials were more team coordination based but less individually powerful, sounds good right? WRONG. This just made the special design of the game insanely obnoxious with the unholy trinity of Ink Armour/Tenta Missiles/Sting Ray being the primary reason I never want to play this game again.

Onto positivity though this game does do a lot of things right. Pretty much all the new weapons are fun and octo expansion is a fantastic single player campaign (we don't talk about the base game's campaign okay). I love Pearl and Marina they're awesome and the music is great and most importantly the game is generally fun but I feel due to all the negatives in the future this game will be seen as the black sheep of the franchise.

yeah this kinda sucks the actual gameplay is fun but THATS IT and the singleplayer is uninteresting

Great game but weird choices were made when porting it like making one player always have to be an easy mode character and everything about this game is just sort of sterile and uninspired even if the level design is great

DONTO WORRY DO YOUR BEST
NANANANANANANANA
PIKU NIKU FEEL SO GOOD
NANANANANANANANA
um I can't make out the rest I don't know japanese but this game rocks

Great game but I lost all motivation to keep playing after reaching the final point of the game which makes sense but idk mixed feelings

Peak maybe idk I kind of suck at it but I also love it
