Lego Star Wars is good, senseless fun that is brilliant in short bursts for the constantly travelling. However, it is utterly plagued by odd freezes. If you have patience for a restart once in a while, it's enjoyable brain-free lego beatings.
Monster Hunter, of course, is the king of the console. Best looking, best playing game out there, but with a learning curve that could be an event horizon.

Same thing happens to me.
Not too often, but on a random occasion.(Mainly on the Return of the Jedi 1st stage). After that, nothing really.
Once again, MHF2 is great.

Also, may I suggest LEGO Indiana Jones. They fixed the random crashing and it looks and sounds beautiful.
