The commentary on White's 8th move is invalid PGN, as the '{' comment delimiter
pair was used twice. Comments embedded inside other comments must use different
delimiter pairs. Chessmaster accepts both the '{ }' and '[ ]' pairs.
As for size, I have been able to successfully import a file that was just over
3MB in size containing over 4000 games, BUT they were all Ruy Lopez....
