Good, competitive Mini Games?

There's no real 'list' or anything, it depends on the host. I generally run a similar set, usually starting with Tremors, then Cat N Mouse, and moving on to some different style games, then coming back to that with games like Tremor N Mouse or Tremor Blast at the end.

If your looking for new minigames, you may want to a. participate in TGIF, b. or in a minigame game in the Customs Lobby, or c. look through the Featured section for minigames, those are the bulk of what's played generally.
