Honestly, even when I play a pin out in the wild I find it very hard to determine whether I will really like it at home. Its so frickin loud in most places that you cant hear the callouts, and figuring out the rules on a pin can take some time...More time than a game or two allows. At least for me, I like getting them into the gameroom, then really diving in. I may end up liking it or hating it (pretty rare that i've 'hated' a pin). Then I sell it or keep it for a while.
If they had a netflix for pins (pinflix?), I'd sign up.
so yes, I've purchased MOST of my pins after either only playing them one or two times or not at all.
