Play RE5. It’s the second best in the series. Also, I agree with Revelations. I never understood the hate it got. Rev2 is a little more understandable but Rev really tried to return to the survival horror roots which was nice to see.
Oh man, I played the heck out of RE5 back in the day. XD I've actually been dying to replay it lately. I would ask for us to rent it from the video store all the time before finally getting my own copy, and I played it over and over trying to get all the S ranks and unlockables I could.
I think I get what you mean about Revelations 2, too. I've only played the first chapter back when it was new, 'cause you could download that for free. I still liked it, but it was probably one of my more lackluster RE experiences.
