1 and 2 are available. 2 is sub-titled Crimson Butterfly I think.
Finally got Resi 4 after 2 weeks waiting

(thanks Mr Customs 👍 ).
Anyway, so far really enjoying it except for one thing, the crappy controls. Honestly does Capcom think we're still in the 90's. For a Special Agent Leon is useless. He can't even walk backwards and shoot, turn round whilst aiming or look around corners. He must be smoking something because he can't even turn to his left or right at any speed.
I know why Capcom did it. With such controls you are very likely to panic and be smothered by scythe wielding psychos. It's a rather basic and simplistic way to increas the difficulty of the game. I could think of several ways to improve the control of the main character. But maybe it will make the game too easy? Well I guess I'll get used to it. But nowadays it should be better than this (it is with Capcoms Devil May Cry, though that is a different kind of game).
Griping aside I am liking it a lot. Only been playing for an hour or so. Long way to go yet!
