Stealing vehicles from a base is the lame, seriously, if you think about it do you think one measly little rebel could just zoom in with a speeder and hijack a TIE fighter? No, thats rediculous.

I am all for not being able to steal arial vehicles, and certain land vehicles including the ATAT, ATST.

Han Solo are different because they have done that kind of thing before, Chewbacca probably had some expirience from the clone wars. And Han Solo from the Imperials, and he even says that they have snuck into other places before, which means they probably have a good understanding of imperial proceedures and vehicles.

And since Chewy and Han aren't in the mod I don't think stealing complex land vehilces should be allowed.

While making a game, dont forget the gameplay itself. Even if you want to make a game close to certain lore. And why cant a rebel sneak into a base and steal an enemy fighter or whatever? If someone is a master of stealth, the theft of a vehicle will be successful, Im sure about that.

I'm advocating locked vehicles largelly for the sake of game-play, as I've already stated.

Talking about game-play...
