sorry i didnt read all the posts but; there is no need for orbital atm. just check out zaphodx's games. no orbital fights what so ever And how are tanks faster on the ground than orbital units...in orbit...??
I would be happy if the orbital layer doesn't exist. I feel it has a role as a logistics and intel layer. I think the laser platform is cool. However, I think currently that there is a very "spaceshippy" feel to the whole thing, and I'd really rather prefer keeping the focus on creating very good other layers, with the orbital layer simply being for logistics, intelligence and delivery of weapon systems (nukes, kews, etc. )
