There's a boom right now in online mobile gaming like LAN gaming and MMORPGs, will this platform support those kinds of applications or will it be exclusively PWA content?
It would be like playing an online game without installing it, it would be like old online MMORPG possibly, like gaia online, I can't really remember but it doesn't need to be installed, just takes a long time to load. That's just possibility. Not really sure if it's compatible at all. No offline functionality in case.
Gaia online isn't actually a pure gaming site and I don't know the last time I visited it but it was slow back then. If the app store supports MMORPG then it won't be PWA.
