By the way Tom, Race for the Galaxy has once again become my family's favorite game. It hits the table a couple of times per week right now and we plan to pick up the third expansion this week and the new expansion whenever it comes out.
A couple of years ago RftG was our favorite but was eventually replaced by other strategy games and sat unplayed for almost three years. A month ago one of my sons suggested we play and my three sons and I all fell in love with it again. You made a great game!
