Tree Tag is a fairly popular game. You can choose to be an ent or an infernal. If you are an ent, you need to survive for 30 mins and run away from the infernals while trying to make a base without them knowing it. If the infernals kill your main "ent" your whole base will die and you will be summoned to the center where you can be saved by your teammates. If you are an infernal you must hunt down all of the ents before the time is up, making sure none of them gets too strong and builds an army to fight back. This game is recommended for 3v1, 6v2, or 9v3.
A good simple game. Not one that you would play over and over again, but a great game to play when you want to take a break from others.
