Eastercons usually have a games room, where board games, card games, role-playing games and other games are played througout the day and late into the night.
What sort of games are played?Edit
Could be anything from card games like Munchkin and Werewolf, through to standard role-playing games. And usually you are very welcome to bring your own games (commercial or home-made) with you as well.
What is the structure of the games room?Edit
Typically there's a room with a number of tables with chairs, and a big stack of boxed games in the corner. There's a whiteboard/flipchart with the names and times of games that people are planning to run and a chance to signup for them ... but there's also people starting short games or looking for additional/replacement players, so just drop in when you can and you'll often find a game to join.
