I rented Deus Ex. Its fun in the "change of scenery" point of view. Its not groundbreaking by any means. Good graphics. Kinda like a cross between Splinter Cell and Metal Gear. I only got through the first level so far so if it gets better then I'll edit.
Edit- So now Im hooked and trying pinch pennies to get the game. I think I already blew at least ten bucks on renting it. Its alot like Metal Gear. I didnt play the new Metal Gear (even though I had the MG4 PS3 bundle.) I traded it for a couple of games instead. Deus Ex has a lot of the stealth priority along with the roaming sentries and video cameras that I remember on the other metal gear games. Theres no MP so Im hoping that its a large game. At least large enough to justify spending $60 on. Its funny, I just signed up for Blockbusters online membership expecting to rent Deus Ex but its not available till Dec. yet they promote their catalog doesnt have the 28 day waiting period like Netflix & Redbox. I guess theyre referring to movies only. CRAP!
So I definately recommend it. At least rent it to see if its for you. I give it 5/5 stars.
