What is that?Move compatibility.
I've always heard that the PC version was the worst, but now I have forgot why. Did it have something to do with graphics? PC versions usually have better graphics but maybe RE4 is an exception. If keyboard+mouse was the problem, people could get a gamepad.
I got excited when I recently heard about RE4 HD, but I have read that not everyone likes it.
This quote of Bruno is an excerpt of his post in another thread:
RECVX HD and RE4 HD are actually not worthy if you have the games for PS2. The HD is not very well implemented, it actually looks worse in HD since the poor aspects of the game's visuals (textures, etc) are even more evident. You can buy them separately, so you could buy only RECVX HD if you don't have it for the PS2.
To answer this topic, I don't know which version I would like the most if I tried them all. But I'm very happy with my PS2 version.
