This was clearly a down year in my games played in 2010 with only two "nickels": Thunderstone and 18xx. A few games knocked on the door: the perennial favorite Magic: the Gathering, Castle Ravenloft (I've now hit five plays in the last month having played it the last two days), Claustrophobia, 7 Wonders, and Time's Up. I guarantee that if I owned 7 Wonders it would have made the list!

Having already played Thunderstone twice this year (once trying it out solo, once with Matthew) I'm confident that it will at least be a nickel in 2011.
