Day 8 - How can we get more people playing?
Geez, you don't ask the hard questions, do you?
One of the best ways to bring in new gamers is to raise the next generation of gamers, of course, but this takes time. :) After that, it's important to encourage new gamers to the hobby by emphasising the positives about roleplaying games - social interaction, improving social skills, learning the application of basic academic skills (notably mathematics), the cathartic properties of engaging in fantasy/science fictional/etc. violence, as well as the stepping out of oneself temporarily and being someone or something that you're not (but might have fantasized about being). There are plenty of genres (and sub-genres) of roleplaying games that we, as gamers, should encourage potential players to explore the hobby in a roleplaying game whose genre appeals to them.
Anyway, that's all I've got on this one. Look forward to reading the views of other people on this day's question. :)
