Got it working. Slow download, but it was worth it! The character models are last-gen, but saved by a nice quirky design typical of Eidos, the scenery is detailed and interesting, the gameplay... well, you're led by the hand in this, but its fun and full of different turns. Music is great, although the fake rap is kinda pathetic. Stereotypes about as usual too, Hitman is famous for them.
What does blow me away is how this ran on my PC, which I keep quite clean for playing games. Nothing here taking up space. With all the next gen effects, minus aa at 1024x768, this game has framerate issues. It's an average spec, getting on a bit... Athlon 3000XP, 1.5GB PC2700, Geforce 6600GT, A7v8x... the mobo is fast enough for the components, it's not a truly slow PC and ran BF2 and SC:CT with no hiccups. But Hitman showed the difference between it and the 360. Even with all the ram it ran slow. Makes me happy I got a 360 as upgrading this baby would take more that just a new g-card...
