Weston, of course I was joking
But the problems are essentially 2:
1.I don't want to disassemble my pc any time I want to play (virtual cd hide and tetris are already too much for me!!!)
2.I have a laptop, so it's not so easy to unplug drives, at least for me.
No way, I'll leave my copy of GT legends on the shelf of the store (and buy F.E.A.R. instead ^^).
