Would it be worth having a sub-forum dedicated to adventure game devs? A place where people can both show off what they're working on as well as ask for help and guidance in getting started with it?

Hey, LHG. Definitely worth considering, and we've always wanted the forums to be a dev-friendly resource. We'll probably keep things as is for a while, as we'd rather start simple and build out than open up a bunch of little-read subforums too soon. But we'll certainly talk about it!
