One thing is that default minigames are still really annoying during the ghosting phase as you can't see anyone or defend yourself. An invite or something that popped up as it finished would be nicer.
Too bad that wouldn't work too well.
1) Server doesn't know when you're ghosting or not.
2) People could just ignore the invite.
The best solution is to make a spawn room with no possible weapons, or a safe zone.
That happens no matter the minigame though. In a DM you can get spawnkilled multiple times that way
Stop respawning.
