One of the most exciting things about game design is how quickly interest in the topic is spreading. Games are growing, and as they do we’re seeing players become more and more sophisticated about what differentiates the best ones. Increasing access to game developers for major titles is also encouraging people to think about design–if only so that they can convince those devs to make the changes they would prefer.
As interest spreads, so too is game design writing. The Links page has some longer-standing resources. Keith Bergun has now begun collecting design blogs that started in 2016. I’m looking forward to taking a look at them; if you’ve got a suitable blog, please do add it!
