Sadly I think no one will ever pay money for games for an unadvertised, not-sold-at-retail, open source game platform, which means people aren't going to make quality games that cost money to develop, which means adoption will be all the lower. So, that means it's not "viable" in a commercial sense. I would rather like to run a sustainable business, which seems more plausible with the playdate than anything else on the market outside nintendo/sony.
