In Attack Wing (star Trek) there are ships which can reverse!
I have been playing a few games of attack wing this last week and I have to say I don't prefer the system but with a few tweeks I would love to do it for capitol ships in this system.
But reversing really screws up my world, especially combined with 180 degree firing arcs. I mean how the hell can you plan for it? You want to get in close and suddenly he is movement 2 further back...
