Every single ground combat mission forces me to change discs. Every. single. one.
FFFFFFFFFFFUUUUUUUUUUUUUUUU
If side missions are to be all jumbled up on the two discs, the mission screen should list what disc each is on so you can clear them from disc 1 before going on to disc 2.
I agree, just started the intro and this news has really pissed me off.
If you install the 2nd Disc why must you still swap? They should have followed what Forza4 did.
