Mirror's Edge, it is a cool concept and the game is quite good but it has too many flaws to make it the great game that it should have been, the game is at its very best when you are running and performing all these acrobatic parkour movements, unfortunately the game doesnt make it very clear wich way you should be going and forces you to stop and look around to figure it out, then most of the jumps are very unforgiving making the fall to your death animation something you see quite often, i know this was probably the way of the dessigners to make the game difficult but it actually isnt that hard its just frustrating that you have to stop so often, basically the game wants to be a racer but performs like a platformer succeeding in neither.
I got Bioshock, Dead Space and Grand Theft Auto IV for 100 dollars, pretty good deal if you ask me, im currently playing Bioshock and so far it has been great.
