I’m putting together a survey for an organization to figure out what would be the best game(s) for a tournament. It would hopefully be team based. Questions like which consoles people own and which games they play and what types of games they like to play. I’m just not well versed in every competitive game. This is in the central U. S. So certain games are probably more popular here. I’m not necessarily trying to find the most popular game but the game the most people would reasonably want to play.
The short answer is something people can play on a phone. Console ownership is not so prolific that you can assume people will have them, or that they will know how to use them properly. To that point the jackbox games are great for this
