Seriously, original re2 didn't have no Mr. X. Only portion I didn't like in the excellent re2 game.RE2R was basically RE3 already. I mean they cut out all the character-zapping/story variation from the original RE2 and doubled down on the Nemesis pursuit angle throughout... which is basically original RE3 in a nutshell.
If we are naming off non resident evil Capcom games of yore to get remake treatment, then I would pick mega man legends series of games, over Dino crisis although Dino was good, mm legends was great, back in the day. Although I can see Capcom messing legends up and doing a better job with Dino crisis as they are good at them, just look at monster hunter.This would be awesome. Dino Crisis 2 was one of my favorite games on PS1.
