NogginBasher: I play monsterhunt sometimes
Boom!: Imagine the starting point being a game where people are not forced to do anything.
A completely free game where everyone can move freely, and really
play a
game as in the true meaning of these 2 words.
This can radically shift the mentality and objective of the game

For example, I have played many games where everyone stopped acting out a serious role, and engaged in one (or more) of the following activities:
- Hide and seek: One person hides (preferably with flag) and everyone else looks around to find her/him.
- Capture record: Everyone joins 1 team to try and beat the fastest record by boosting in multiple tactical places.
- Bunny dance: Everyone jumps around like bunnies in a dancing fashion

- Trick jumps: Try to make an impossible move, path or jump possible.
- Sightseeing: Particularly enjoyable with many (custom) maps, checking out every inch of the environment.
- Bunny race: Everyone goes from start to finish (and back) using only jump.
- Violentless CTF: Grab the flag, run around. When you feel like it, drop the flag so someone else can pick it up or return. All players try to keep the score even; for example make a 1-0 into 1-1. Overtime is desired

- Bunny track: Pretend the CTF map is actually a BT map.
- Follow the white rabbit: Everyone follows the bunny into the rabbit hole - wherever it may lead

- Game of tag: One player is 'it' and uses 1 point-blank range enforcer shot/hit to give this 'tag' over to someone else. But if you manage to kill someone, you must feign death until someone tramples over your head

- The attraction: When you see someone who gives you a funny vibe, keep following her/him in your own way.
There are a few more games I used to play in CTF
