We support digital goods and services as well, physical goods have just been the most popular so far.

We don't have the automation nailed down quite yet so for now you still need to manually process orders.

"quite yet".. does this mean you're working on it? That's exciting!

I want to run a store like www.itch.io (DRM free games) that accepts BTC. I'm also interested in automating microtransactions for games.

there is no reason you can't do that with OB. there is a REST API so you can make your own tools that send the digital good once payment is received.
