Resident Evil 2 is the one game I wish they would just give it the facelift. The DC port was a nice touch, same thing with 3. Deadly Silence was also awesome! The gamecube remake was great too, I haven't gotten the new HD remaster, I will though.
RE4 is amazing, the HD version stutters quite a bit unfortunately, great game though.
Revelations 2 will be released in disc form once they are done releasing all the episodes, I got the 1st episode 'cause I wasn't aware of this but I'm not gonna get the rest of the episodes, I'll wait for the disc.
RE5 is awesome, I play it with my GF side by side 2 screens. Maybe it's awesome to me 'cause of the situation.
I didn't even try RE6, I saw my GF play it a bit, lots of QTE, felt like a cut scene the whole time.
