We've established several simple branding standards for ourselves and others to use in situations relevant to our team.
For headers and other prominent text, we use ADAM.CG PRO. The original font downloadable from most other locations has some rendering flaws in some browsers, so we've made a patched version available here.
For body text on our website and elsewhere, we use Roboto Light.
We use this logo. We frequently modify the logo to fit the circumstances and only want modifications in the context of trying to conform to game theme.
