I haven't played the games. I'm not sure the PC format would be that great to play... I have Silent Hill 3, another console to PC game conversion and I uninstalled that after 10 minutes due to my complete frustration at the shitty interface (being used to first person shooter games on the PC, which are much more intuitive), and I assume that RE probably has a similar interface as SH.

Going by this image (http://images.amazon.com/images/P/B0000524PQ.01.LZZZZZZZ.jpg) Nemesis looks a lot like he does in the game. He walks around in what seem to be New Rocks weighted down with lead :P He's cool, though there are things that make little sense... but that might spoiler the movie, so let me know when you've seen it then I can mention them.
