I think these would make for some great rules to speed up gameplay. Got them from an article at Cracked dot com.
1. Both sides have to have an equal team. One guy can't have all the grenade throwers and machine gunners while the other just has a squad of people pointing to their left.
2. The only exception being if one side has a base. If that's the case, the person who has the base has less soldiers. This works well if there are only 5 yellows, but 15 greens.
3. The game progresses by pointing at one of your soldiers, or grabbing him, and making the appropriate sound effect. The power and effectiveness of each soldier is based entirely on how good your sound effects are.
4. When you've done the correct sound effect, you then tell the other player who got killed. This is accomplished by grabbing the other person's guy, making a sound that signals death ("uurggh") and knocking him over.
5. The other player can challenge this death if he thinks that the kill was unrealistic.
Some common challenges:
* No - he can't die because he was behind this stick.
* Why are you making machine gun noises when he's got a flame-thrower?
* No but wait, my tank got in the way (move tank in the way).
* You can't kill him because he's my captain and you can't kill captains because they're stronger than the others and anyway he's on a secret mission so actually your guy is shooting at nothing because my captain is hiding and he's only pretending to be dead.
* You're stupid.
