Question 3: How do you find out about new RPGs?
I wouldn't say I was in any way at the front of the curve when if comes to new RPGs. New miniature lines and games, yes, through facebook groups and podcasts, but RPGs less so. My social media bubble for RPGs tends to be limited to games I already know and love. However, if a new RPG comes up in one of my podcasts, for example, I'll hear about it. What I'm unlikely to hear about early on is games outwith the genres I am already into.
So, podcasts tend to be my largest source of RPG related info, with the odd RPG blog I follow (intermittently) as a secondary source.
