Personally I think blockland's vehicles shouldn't be large/ huge. Vehicles that you could normally walk around inside really seems to turn me off when I combine the two in blockland. Vehicles should be limited to ones that you would sit in during the entire time,( Jeep, stunt plane, magic carpet, tank, etc...)and not vehicles that "Could support a whole crew"(Spaceships(single riders okay), Aircraft landing pad boat thing, large boats,ect...) Also, blockland doesn't really support those sort-of things like other games do, so I think it's best to leave out.
