General board game sites:

BoardGameGeek – Great online forum for all things board game. They have a super-fantastic, always-updated list of internet board game resources.

Vintage Board Games blog - it is what it is.

Manufacturing a game:

Right now the best I’ve been able to find for online, on-demand, board game parts is the The Game Crafter.

For digital prototyping there is VASSAL:

Vassal is a game engine for building and playing online adaptations of board games and card games. Play live on the Internet or by email. Vassal runs on all platforms, and is free, open-source software.

Selling your game:

Publishing Guide – You guessed it, this covers how to get your game into the hands of a publisher. This site also has more info on their regularly updated blog.

Every year there is Board Game Jam in Toronto!
