The GCN versions of the RE games were definitely worth getting as they did improve on the original versions. However I played all the original PSX versions of the games, and the original DC version of Code Veronica. However I did by RE:0 and RE:1 on the GCN and they were both great.

But for survival horror you still can't beat the first Silent Hill game. At the time that was amazingly immersive and very creepy. The surround sound and dark ery short viewing distance of the fog really did work very well. I really need to get hold of the last twl SH games.
