Design
Gamasutra is not only great for keeping up with current developments, it’s got an amazing library of past articles available.
The Kobold Guide to Board Game Design is $20 and worth ten times that. It’s (obviously) focused on tabletop, but a ton of the content is theory that is applicable to any sort of design process. The other Kobold guides are also rad.
