Ummm... My suggestion was slightly altered in translation 500 Robots was the Spawn limit... the pool we could draw from.

The starting good guy units would have been 50 or less(though the spawning mechanism would technically be good aligned at first)  and then the idea was that we would have mechs "spawn" from that pool of 500, while bad guy or good guy spawns of lesser #'s occur weekly, then on top of that players from either side could hack the other's active units(or the pool itself) to get more on their side.
