I downloaded the Half-life 2 demo on my 1.6Ghz P4, 512MB, 64MB GF2 PC and it ran surprisingly well with low settings while still looking pretty good. This game is amazing! I think I just might buy it. I hear there is a free mod version of Softimage specifically for half life 2. If so is it only for creating game models/characters or levels? Isn't there a Half life level editor?
