Oh yeah this game is awesome! But why...
Pros:
-Great story
-Cinematic gameplay with cinematic voice acting
-Re-playability for multiple endings!
-Great Graphics
This game also has A LOT of context sensitive sections (ie: press x not to die). So if you don't like that stuff then this game isn't for you. but there are other reasons...
Cons:
-Can get difficult at parts (mainly at end)
-Sometimes you might end up killing your self in the game (the sanity system is hard to get up at points)
-Some few glitches but no game breakers or immersion breakers.
I should explain the "sanity" system. The sanity system that Indigo Prophecy has that means that if you see/do something that your character doesn't like (ie: see a dead body) their sanity bar will go down. But if you do something they like the sanity bar will go up (ie: drinking coffee). Now I played this on PC so the graphics might be worse on the Xbox (same with the controls). You can get this game on Xbox 360 for 1200 Microsoft points or you can find it for 10$ on computer. Now I say you should buy it but of course it's up to you!
