Just yesterday, we were brainstorming about how to recruit for beta testing as well as advertising for the game. Such as:
1. make flyers about the game and post it to local colleges and universities
2. ask stores around us if they would allow us to setup a station where people can just come and play test for a day. Have signup sheets ready, of course
3. setup a web demo with link to a form
Nothing new, of course, but it hadn't occurred to me to try these things until recently. We are hoping to get a demo out soon :)
