Some games have what I call “grabby”. That special something that makes you feel, viscerally, the desire to play them. For me, Dogs in the Vineyard has it. World of Darkness had it. It didn’t have it when I read it, but after playing it, Apocalypse World has it in spades. And I’m beginning to suspect that Becoming Heroes has it.
Rob Donoghue has recently mentioned that it takes more than being a great game to get a place in his collection. I think that, for me, grabby is part of this additional something. So what’s grabby? I doubt I can answer that, but I can at least explore it.
