Metro 2033 - Utterly boring. Some decent atmosphere but I haven't been railroaded this hard since CoD or HL2Ep2. The ENTIRE GAME was just waiting for slow walking Russians to get from point A to point B. The few segments where you were allowed to play the game almost worked but by the time they got going, you were leashed again and made to just walk along with slow moving Russians again.
As a counter-perspective, this is what sold me on the game. It gave you time to soak in the atmosphere, and gave the game pacing. If it was just a go-go-go kind of action game, a lot of the game would have gotten lost along the way.
InMomentum, the daily deal, was a decent game, but falls way short of a 9.99 release and is still hard to recommend at 4.99. If you were a huge fan of CounterStrike jump maps, you'll probably get in to it. Otherwise, I don't think the mechanics will grip most people. With no actual reason to play other than "get a high score," the game didn't keep me for long.
