Question for the Resident Evil fans out there....?

I would really suggest you play the first 3 for PlayStation then play these too. They're all great. The order is 0, 1, 2 and 3 run together at some point, Code Veronica and then 4. Outbreak covers events from in between 2 and 3. It's well worth playing. 4 is the greatest game you'll ever play :) Then, 5 comes out soon, can't wait!
