Ah, I see. I knew that the original translation of RE1 was kinda terribad (Jill sandwich et al). I was thinking that Barry's backstory/motivations had been changed in the REmake, but if it's only the tone of his dialog, then I guess I'm covered to play RERev2.
Also, RE3 is considerably harder than RE2... wow. It's kicking my ass.
I usually play every RE game on the hardest difficulty possible on my first run through the game. In terms of difficulty, I think the harder RE games (judging off the hardest selectable difficulty you can choose out-the-gate and not unlockable difficulties) would be:
01.) Code Veronica (especially if you don't know how OP the knife is)
02.) Revelations 2 (it's legitimately challenging on Survival)
03.) Revelations Unveiled HD (a bit of an unfair advantage Revelations 1 has is the console/PC version had the 'remixed' difficulty mode, Infernal, unlocked out of the game. If going by the 3DS original, it'd be much lower).
04.) Resident Evil 3: Nemesis (it has its moments)
05.) Resident Evil REmake (I think the beginning is the hardest part on Hard)
06.) Resident Evil: Dead Aim (this wouldn't be nearly so high if it weren't for that FUCKING FINAL BOSS ON HARD Eqwaslsdlfkgkdf)
07.) Resident Evil 2
08.) Resident Evil 5 (while plenty of supplies, some encounters are tough on Hard)
09.) Resident Evil Zero
10.) Resident Evil 4 (pro difficulty is challenging, but you can't go higher than Normal first run, which with constant savepoints and surplus supplies, is middling challenging)
11.) Resident Evil 6 (even on Professional, it wasn't that hard of a game, a few moments, but manageable if you got the mechanics down. Wasn't able to play No Hope out the game, so didn't experience that first)
12.) Resident Evil 1 (this is a bit hard to judge, I decided to go with Original as opposed to Arranged in the DC as that should be played after the Original as its basically a different game, and honestly, RE1 isn't that hard if you have tank controls down).
13.) Resident Evil Survivor (helplessly short and easy, meant to be replayed but I think very manageable on Hard).
That's just my personal opinion off the top, though. Need to finish Gun Survivor 2 and the Outbreak games though, and didn't include the Chronicles games.
