Alright, here's mine, from top to bottom:
01. Revelations 2 – My most played game on Steam, largely due to Rape Mode, but I’ve also played through the campaign at least five times. Only minor complaints concerning Claire’s dullness and Ada’s absence from Rape Mode.
02. RE1 / REmaster – The one that started it all, and the one I thought would never be dethroned. Incredible atmosphere, several game modes to keep you entertained, and Twink Chris is still the hottest!
03. RE2 – Introducing three of my favourite characters to the world of Resident Evil, had a history of constantly fighting with RE1 for the top rank of my list until REmake came out.
04. Nemesis – The first RE I ever played, it will always have a special place in my heart. Jill is awesome in this one, Nemesis is a scary stalker, and we have a sexy Latino whose accent drives all the foxy ladies crazy, what else could be asked for?
05. RE6 – Probably the second most hated RE, but my second most played game according to Steam statistics. To me it’s a bigger and better version of RE5, which was already great.
06. RE5 – Doesn’t feel a lot like RE to me, the least interesting and most predictable story ever, but still a lot of fun to play, especially with a human partner.
07. Operation Raccoon City – The most hated game with RE in its title, but I like it, especially exploring those interesting characters and their abilities to find out what works best in which situation. Must be even more fun with three human teammates.
08. Revelations 1 – Loved it at first (see my review for details), but the campaign quickly got boring after the first time. No replay value at all, I would never have touched it again if it wasn’t for Rape Mode.
09. Zero – Could have been so great! But no boxes = annoying item management, many unnecessary doors = too much loading. You spend half of your time switching items around and looking at door animations. Finished it once, tried all the outfits, I'm good for now.
10. Code Veronica – Too long, too hard, too much backtracking, ugly grey fog instead of darkness. One of the greatest stories and sets of characters, but the gameplay just didn’t click with me. Finished it only once.
11. RE4 – Terrible PC port. Slow, unresponsive controls. My least favourite version of Leon. Nothing else to keep me interested either. Never finished it.
