I know this may be a "longshot", hehe. I would love to see a special kind of mode where you could just spawn the bots and have them fight each other.
Dev's should make a flash game based on MNC. A turret defence game, where you can make the turrets and pros in the game kill bots like sudden death blitz, until you can't hold bots any longer. And an additional game mode where you have a bot lane and the enemy has a bot lane, and you try to swarm the enemy with bots while defending from his (2-player or vs computer). I'd play it much more than bloons tower defence, and that game gets a lot of popularity.
