>As for a more official way to distribute them, we’re still exploring different ideas for the best experience of getting games out to Playdate owners.
For a product advertised as a hobby device for devs and gamers, not having a distribution system planned for user made games is not going to help this product thrive.
Things like this tend to be made or broken by the community that builds around them. Look at something like the pico-8. Not exactly the same product, but the markets for them I imagine certainly overlap. The Pico-8 makes distribution of community created content a priority, something that's definitely been instrumental in its success.
Without a community of devs that can support the Playdate and a system they can use to easily distribute content, it's not going to last long.
It seems backwards to try and build a community of devs around a product after it's released. I seem to recall at least one console that died sometime in the 90's for exactly this reason.
