For those curious about "I am Alive", this is what it is
it is not a realistic survival simulator like i believed. It's a 3d mirrors edge (not exactly tomb raider because it's more about adventure) and it's semi-open world. There isn't really any challenge. By the end of the game my inventory was loaded with supplies and i had a bunch of bullets. The "combat" is interesting and neat, but it's all you ever do. There isn't really any replay value either.
I'd give it a 7/10, but don't buy it at that price. It's on XBLA and you should not get it at that price. At least wait for 75% because it's pretty likely it will hit that at some point. It always does.
