Dude, FC is in 3D, that takes care of most of your problems. A 2D game can't have dismounting units. Who cares anyway?
GBG is a MUCH better game overall. The multiplayer rules, and that's ALL that really matters. Single player is okay, but once you've beaten it (FC was EASY!!) there's no point in playing the game. FC really lacked in the multiplayer department. It also was really buggy.
Now, GBG isn't exactly Star Wars realistic, but it's FUN. FUN matters.
