Yep that's this Saturday, which also happens to be a super special day, it's my birthday. My local gaming group the Fenland Gamers are holding a gaming session Saturday lunchtime to early evening. Register at the groups forum for more specifics, like location etc.
My biggest problem is deciding what games to take along. I'm thinking a mixture of “gateway” games, games on my pile of shame, gamer games.
Most LGS should be doing something for Saturday, so it's worth looking them up and finding out. Who knows they may be one of the stores with a rare Tabletop store kit for the day, and you can pick up a promo or two.
