I've got RE5 and it's... well... "stupid fun", that's what I would call it. It's no RE4, but it's fun, was clearly programmed with Coop in mind, looks gorgeous, the story makes absolutely no sense, almost the entire cast is made by dumbasses and Mercenary mode is fast-paced and action packed.
Oh, and there are a few horrible, horrible quick-time events*.
SO i wouldn't mind playing it online, if someone wants to.
*Disclaimer: I played without a gamepad so those the QTE might not be as bad as with a keyboard.
Oh yes I have played this game more than anything else. I think I have a few missions left to replay on the hardest difficulty. I was crazy and also bought it for PC Was a little hard adjusting to the fact that now I don't have unlimited magnum ammo
