I'm not sure which game(s) I would say I love since I haven't played very many, and the ones I have and am planning to play are already considered classics. I guess I'll credit Mortal Kombat Deception, and the other MK "3D era" games in general.

The game that I hate the most is Megaman X Dive. I wouldn't call myself a megaman fan (and I would in fact say that most of the games are baby games) but I played the first three X series games and the entire Zero series. Megaman X Dive is just a pay to win gacha game however, which I decided to play because why not, and it's horrendeous. The game is on a smarty pants phone so you just mainly walk forward and mash a button to shoot enemies. It's also pay to win because I was horrendously underpowered to the point I couldn't continue the game.

But this is already getting convoluted, so the thing about that game? Capcom recently shut off the online servers for that game, are gonna put it on steam for 30$ (formerly f2p game mind you), and they've created megaman NFTs. Funniest but also the saddest shit I've ever seen.

(Edit 1: There are six games from this series on the NES, and they're considered staples. They also oversaturated the market of them in the mid 2000s. I think it's safe to say that this was one of Capcom's main franchises at multiple points of time, so how could it stoop so low?)

(Edit 2: I just remembered the Metal Gear Solid 3 Pachinko machine. If I were a pessimist, I would guess that any franchise would fall at some point.)
