I live in Manhattan. I'd love to meet some other people who play heavily on isotropic.
There's a gaming shop I only recently discovered in Williamsburg, Brooklyn, called Twenty Sided Store. It's a 3 minute walk from the Lorimer St. stop on the L. The store has board game nights every Thursday. They have a number of games open and freely available for anyone to pick up and play, but they only have the base set of Dominion.
What if we tried to organize a meet-up at Twenty Sided Store during one of their board game nights where we each bring an expansion (or better yet, our own pre-designed kingdoms)?
