With a bunch of players I could see it working!
I'd try to do a StarCraft comp stomp with my wife but we always ended up huddling together on one part of the map right from the start, to avoid the 1 CPU opponent's obviously-cheating horde of like 30 hydralisks 4 minutes into the game. 😂
To add: I just remembered, a lovely RTS called Metal Fatigue was an AWESOME game, but it was so bad about this! Your giant stompy mechs couldn't go underground, and the pathfinding was terrible down there, so standard match end-game was usually about sending swarms of tanks through tight tunnels looking for the enemy's like, one builder unit, before the game was considered won. 😂
