I'm running.. p4 2.53 / 512 meg ram / WinXP (which I installed only for this game.. so it's pretty clean) / nvidia gforce 4 mx
and DAMN.. did it drag if I had anything cool like high resolution/detail or any of the advanded features. I think it's my video card, and I plan on remedying that soon.
Still, the game was good. Sometimes the darkness got annoying, but I enjoyed it.. I'll be back to it tomorrow.. for now.. sleep (and then work

).
