I have been also in these kind of games and I miss a "leave button".
Penalized? Of course:
Miss your bet points and the result should be "defeated"... But at least you don't spend more time in those games.

We'll let you get a replacement in all your games, but not a select set. Otherwise people would just sub out anytime they're doing bad in a game to keep a good record.

Don't quote me on this but if you find someone that is willing to take your spot and email the mods about it I think they can switch you without you being penalized. That would require you finding a sub before you left the game though.

So, you’re saying you want to be unreliable but not be penalized for it?

There are honestly a few games I'd be down to leave even though I paid to be in them, and I'd honestly be willing to just quit without getting my credits back. The only problem is I lose reliability for not being active so some games feel more like a chore than an actual game. Would it be possible to have a system to quit games in the future or am I just entitled?
