I am also having problems with gameloft games, I have tried shasow guardian, nova and sandstorm and they all start running but after some seconds the exit to the home screen.
I also have the problem about dead space, I have bought it from market, installed it and when I run it, it says that need to download data from the server, and after that, an error 5002 comes. I have contacted the support of EA and they have not been anle to give me a solution, so I am going to get a refund.
I guess this problems are related with compatibility problems with ICS, is so new that the developers haven´t prepared their software yet, I am afraid.
Best regards.
