I just finished replaying it, the only thing that truly sucks about 2 is that all the loyalty missions are quite short and uncomplicated compared to a main ME1 planet. There's nothing in the game comparable to transitioning through all the stages of a main mission in the first one. Even though plebs bitch about the Mako, it was really integral to making the main missions feel like a significant undertaking, because it put a lot of space between starting hub areas and the thing was causing the trouble on the planet. It becomes especially evident when playing some of the DLC missions which are actually longer and more fleshed out.
