There’s definitely a ‘play to your audience’ here, because we used EATPM and Radical at IFPA13 and was overwhelmed by the requests to set it as single player only (we weren’t planning on doing it originally).
As always with respect to format decisions, WPPR decisions, game setup decisions . . . listen to the players that are participating in your event. I think Doug Polka brought that up on PAPA TV last night and it’s a good golden rule to follow.
