What’s the definition of “all powerful”? Would an all-powerful being need to be able to draw a square without it being a rectangle? Or to build a house without walls?
If the answer is “no”, then I’d argue that the left most arrow/conclusion is logically wrong/misplaced/invalid. Assuming that “free will” is not possible without “evil”.
In my experience the most popular and fun “party games” are boardgames such as Top Ten, Time’s Up, Hot & Cold or Codenames (more or less in that order). They work best for 6 to 10 players. Though I don’t think they shine in a highly competitive tournament setting.
Randomness exists in all of these games but I consider it very balanced/smoothed out so it shouldn’t really affect the outcome. Not all of the games I mentioned have permanent teams, but that can easily be changed with house rules.
