Deus Ex is quite polished. The story/acting is pretty rough, but the gameplay feels astonishingly natural. Except for the movement virtual stick. It's 8-directional instead of analog for some damn reason.
Two other great games this week are Tiny Thief and Ravenmark: Mercenaries. Mercenaries is a free-to-play, multiplayer version of iOS's best strategy title.
