Just recently participated in a group-play 3-strikes format, but instead of 2 players in each 4-player group receiving a strike, everyone but the 1st place finisher in each group received a strike.
At first, I was not a fan, because this format doesn’t differentiate between 2nd and 4th place at all. And my first game there was a 17M Dr. Dude score for 2nd place vs scores of 2M and 3M for 4th and 3rd… and 17M got you the same result as a 2M score. (thankfully for me, I put up 22M)
I think I still prefer 2 players per group getting a strike, but as the format continued, it wasn’t without its merit: instead of focusing on first beating just the next score above you, it forced you to always be aiming for the top score, requiring players to go for more high risk/ high reward strategies in a match play setting. It turned out to be fun.
