Not sure I'll be getting a Vita so I won't be getting any of these- a replacement for the PSP I've got is fairly necessary at the moment, though. (I sort-of drowned it). The PSP LEGO games I've played were just as good as the console versions, though - I hope this'll continue, and I'd recommend PSP LEGO games as a good alternative to the console ones, though headphones are a must if the speakers on the Vita are anything like the 1000, 2000 and 3000.
It's not illegal, it's just cheating.
I'm into exam time right now... I'll be checking up frequently, but I don't expect to be posting in the next two weeks or so unless something really catches my eye.
