This sounds awesome.
- Make a part where control of the unit shifts randomly from player to player
- Make an obstacle out of cpu nukes
- When they're about to win, make it so they can't touch the victory beacon
- Expanding on the life thing, give them one life (or however many you plan on giving them) and make it go up to 1000, and then back down to 1
- Play weird music in the background, like Barney's "I Love You" with Civil War battle songs. Add in the Beatles for a touch of realism

- The banning system should ban the person trying to ban the person (confused?)
- Make a part where you have to land all the players' buildings at the same time
- In one of the "avoid the creature" obstacles, make the creature do one less dmg than you're health (for laughs; make the level really hard otherwise, and make the creature unclickable

)
- Make an obstacle where an army of Vultures in running into a wall and blowing itself up and you have to get to the other side without being run over of killed by shrapnel
Well, that's all I choose to think up at the moment. Chew on it. Or swallow it
