Your 80x80 will do, so long as there are arty limits. What I'm trying to avoid is the all arty battle that was in vogue a decade or so ago. 15,000 points of arty and just saturate the map. It works, but it's SO boring.
Tanks (MBT's) were invented to get away from that stuff. I try to avoid artificial limits and rules that take advantage of the game system, so if my opponent wants 50% of his points as arty, fine, I want a map big enough to maneuver on to avoid that arty. Not that I'm saying you are a red leg, but just so you know where I'm coming from. If you need a small map due to memory restrictions on your machine, I'm good with that, we just need to agree on a limit to arty.
