You can't compare this to the first Deus Ex title. It's really a completely different thing altogether. The first encourages you to explore, and gives you new parts of the world to go back to when you have new abilities -- this one is more focused on FPS elements instead of environment exploration. The parts where it fails is where the first succeeded, and vice versa. The color palette will make you sick after a while. I'm trying to force myself to beat this before I play the next one in the series, but every time I come back to it I get tired pretty quick. Whereas with the first, I tend to get sucked back in and can't put it down again.
