The thing we need to remember (in my honest opinion) about those two minigames is that they are intrinsically connected to Favoritism.
Favoritism cannot be separated from these games due to their very nature requiring a majority vote. If one wants to truly and fully avoid any form of favoritism they cannot play those games. No matter how you try to spin it there will be Favoritism involved. The games literally are dependent on REDs making or doing something that the BLUs like.
Any games involving a BLU vote is also included here.
Alt. Idea: Put a limit of how many REDs can be there if Warden wants to do Kitchen / Theater when it's not LR. Like... limit it to a max of 16 REDs? Similar to Prop Hunt on Hop_v12?
Aight that's enough yapping about Kitchen / Theater.

The original idea to require a minimum of 3 BLUs to use a B.Vote isn't bad and I can see myself applying it during regular gameplay if it becomes official. However I don't agree with forcing the need to use Warden Votes. I think Guards voting in Public chat
* (that way REDs can see that Warden didn't lie about the vote results) could be encouraged if the server's quite full in an attempt to bypass the vote timer taking forever. Warden can count votes while the rest of the BLUs do what they should; Guard the Warden. I also side with Meatloaf in saying that, should the Global Vote become official, REDs will most likely massively vote no (unless its someone they like enough; aka Favoritism) to give themselves a higher winning chance. It's also terribly unfair to the REDs to change the voting system mid-minigame.
I remember that back on SG stating that ties were an automatic No was quite common and I still use it myself to thin out the REDs faster, so removing Warden decision on ties isn't something I'll agree on.
*: I can see people arguing that REDs can and will spam during voting time to make the votes last longer to which I have no real answers for.

I’d rather just have it so that diner and theatre require 3 or more BLUs, otherwise it can’t be played (or it has to be stopped if too many BLUs die during it).
Like I said earlier, that option is unfair to the already dead REDs that have failed the vote and died during the minigame and the still alive REDs who might've wanted to get their turn in the minigame. I could actually see this encouraging REDs that don't like the minigame to massively rebel in attempts to thwart playing it (fair enough). Thus encouraging Wardens to decide not to play them in return whilst they're already underplayed (IMO because I fucking love Kitchen and I'm always happy to play it).
Anyways, here's my current final decision on this: Keep the rules how they currently are. I personally do not see anything that needs to be changed and any changes that I can think of currently has too many drawbacks.
Sidenote: Sorry for the huge rant. I have no brain power left and I got no idea if this stayed on topic.
