Make explosives absurdly cheap. Make other players hard to detect -- limited sensor capabilities isn't really a gimmick, more of a reality of signals processing

Make explosives absurdly cheap. Make other players hard to detect -- limited sensor capabilities isn't really a gimmick, more of a reality of signals processing. One player with enough explosives and appropriate braking power could land himself in an automated factory and rig it to blow in just a few days (depending on the scale of the factory). Maybe add a time-based ban mechanic to discourage this behaviour. "It takes X days/weeks to re-assemble your constituent atoms. Money will speed this process up."
