This has been something I've been wondering for a while... most people here play Dominion regularly online, although I suspect the majority were introduced to the game face to face. But how much of the actual physical games do people here own? And perhaps, why?
I own Base, Seaside, Hinterlands and Prosperity. Started with Base a while ago (about two years), then got Seaside not long after because expansions add a lot, and Seaside was my favourite expansion. Then I was considering getting Prosperity, but decided on Hinterlands (which had just come out) instead because it was cheaper (except, it wasn't, because Prosperity's price had dropped by that point). Finally, I just got Prosperity today from BGG Secret Santa. Yay! And that's also the thing that inspired me to make the thread. I also don't think I'm going to get any more expansions. 102 cards is sufficient, and fits nicely in my card box.
(I wanted to add a poll, but maybe I'm being stupid but I can't see the option to do that...)
