Look, I myself ran a few "pick something" challenges back when I started this game. The difference is that I made sure there was some sort of strategy, or at least depth, to it.
Take this for example. While on the outside, it seems like your challenge, but really it has some depth. First, all rooms are predetermined before the challenge starts, meaning there is a set path for each team. Second, I had given team leaders full authority on what to pick even if the rest of their team disagrees. This was done so that blame is shifted to them for each mistake. This was an intentional design so that the players, right after forming their teams, might have mistrust in the leader. Lastly, the tie-breaker was properly defined by having players pick additional doors. Unrelated, but I did consider making this challenge a classical Monty Hall challenge, but decided against it since it would double the length of the challenge. Anyways, your challenge lacks any sort of depth. It's something your team created either before the deadline or the exact hour after this challenge started. If any of you had quality controlled this idea and realized there was zero strategy, zero depth, and zero creativity, you would've scrapped the idea entirely.
Also, the idea of every player having to PM the host for each selection is already unfeasible and not timely. Just imagine for a second that ten players (some in different timezones with their own schedules) have to PM Athena for one selection. Now imagine the amount of time it would take her to not only get each pick, but to also post the next set. Now imagine that for each selection. You're talking about at least a week for a relatively simple challenge.
"Ideally, this would be done with 10 players in the game, to prevent a three-way tie."
This literally makes no sense. If all ten players vote on the same thing, then there's a ten-way tie. If nine players vote on the same thing, you have a nine-way tie. You get where I'm going with this?
By the way, whatever happened to Not-TDL? Do any of you even know what I'm talking about? I'm guessing some of you are too new to this game to keep that challenge meme alive. Go reread previous runs of the game and you'll get what I'm talking about. You probably should've done that to begin with to prevent
this idea.
