Mario Kart Wii game night?
The old "who has what game?" threads are likely outdated by now, so you might try starting new ones to try to find out who has what now. Gamers are far more likely to trade in console or handheld games; PC gamers are pretty much stuck with their purchases once they're made (though they may not have them currently installed).
I won't turn this thread into a "The differences between PC and console/handheld gaming" essay, but the point remains that our old games list threads may be obsolete by now.
Without an "always connected" messaging system (like PSN for the PS3 and Xbox Live for the 360), we may want to adopt a secondary communication system. Whether it's AIM, Yahoo, Facebook Chat (which users can connect to using any chat client able to connect to Jabber networks), Xfire, or something else entirely, it will help to have a quick and easy way to invite others to join a game at any given time.
Recruiting might also be necessary to bolster the Nintendo Chapter numbers. We may have several Wii and DS owners already active in Tribe of Judah, but not all of those members will own the same games. Of those members with the same games, some may not be able to play at a set time.
There are some fantastic Wii and DS games with online play, but their value is lost amidst the static of the larger "core" gaming community. If you try your hand at recruiting, I recommend Christian forums that don't specialize in gaming. ChristianForums.com comes to mind.
Just some ideas.
Building activity in our console chapters is more difficult than in our PC game chapters for a number of reasons, but there's also tremendous potential in our Nintendo, Xbox Live, and Playstation 3 chapters. It will take patience to see that potential realized.
