I think that in V 14, if it is possible, Badspot needs to make it so that you cannot simply go straight through bricks with vehicles. It is also extremely hard to make a good air fight (especially on slate) when the planes fly right through all of your boundaries. =C
I was going to make an epic Star Wars space battle, but then I realized I couldn't contain the planes and would only be able to use tanks. (even jeeps go through walls)
What does everyone else think???
