What didn´t work for you with Deus Ex?
Did not try TrackMania, but I think a buddy of mine has it. I´ll give it a shot and take it from there....
Deus Ex, I really don't want to start a bone-fire again. Anyway, here's my review of it, I'm not saying you wouldn't enjoy the game, but my review is as fair as possible, make your own decision:

I think you can still play TrackMania Nations for free. The payed version gives you different vehicles (but with the same speed). There are major differences between that one and the new one, and I don't expect the new one to be free on launch, but it looks good. However it's PC only so I'd say play the old one, have fun and if you like it, read the reviews once the second one comes out, check the system requirements and maybe then buy it.
As for Space Marine, there's a demo out (for PC at least, no idea about consoles). Looks fun, can't wait for it.
