For ME3 I hope they take away the ship navigation on the galaxy map. Keep fuel expenditure, maybe, but the actual piloting around of the normandy felt ridiculous. In a game where you're trying to impress w/ the size of the galaxy which is filled with brilliant looking planets and nebulae having something so completely off scale is cheapening.
In the 1st one it could be made that it was simply a scaled map. in 2 since you actually flew around that doesn't work.
