I've played RPGs where you could switch discs, but ME2 is the first one where I went to one place and it said "Insert Disc 2" and then when playing disc 2 it said "Insert Disc 1".
That is retarded.
(I think) every RPG I've played is linear, disc 1, disc 2, disc 3, etc, but if I had to shuffle discs like that I would probably be like "**** this."
Yeah, it's pretty weird.
Disc 1, Disc 6, Disc 5, Disc 1, Disc 3, Disc 1, Disc 6, Disc 2, Disc 1...every time you did anything it seemed you needed a different disc.
