Of the ones that I've played I like RE4 for the pacing and atmosphere. RE2 for the blend of horror and action. Revalations 2 cuz it somewhat got back to it's roots,with puzzle and suspenseful moments. RE1 for the campy script and tense moments, RE3 had Nemesis but other than that was forgetful.RE5 was ok eventhough it wasn't scary. RE6 was shit played through it once,havent touch it since it came out.
