My 2c is to try the funky ideas to get a foothold/differentiator

I think your implicit intuition that indie gamers are keen to explore more titles than they currently (reasonably) can, is valid. I suspect they’re also keen to be involved in early development. And devs are interested in early feedback. So you could introduce something to facilitate that. Or introduce a Patreon/kickstarter type model where you can choose to fund development of games from your subscription.

Network effects are valuable to build in/explore - make it super easy to stream the games on Twitch, Share clips on YT etc. Might help with the chicken and egg!
