I can't run any games made with Unity either. Most of them want a fancy dedicated GPU, not on-board graphics. Not sure if there's another cause on top of that. Edit: but at least they usually open the configuration dialog first, and only crash when I try to actually start the game.
yeah it happens on some of the games, it give options to select resolution and shows keyboard controls. Just 3 of the 15 I tested does that. other shows that thing which I posted. But those which requires GPU also says that your graphics card is out dated or something like that.
I will try asking in unity forum if there is any.
