arwing combat was much too slow and just wasn't as fun

I thought the land missions were cool but they were a bit repetitive and the controls were a little wonky.

But oh man it was cool to be running around and then hop in an arwing or landmaster. They should let you jump in an arwing from a ground level and fly off to a space level mid-mission.
Tha'd be cool.
