Yeah, microtransaction is definitely on my list! I want to have exactly the same as in Roblox. So basically you buy a virtual currency, and have a marketplace where you can buy and sell resources. For popular creators, they can check out their currency and I take a %.
But of course as with everything, this is not a small feature to implement. Therefore I’m now first going with the “pay for premium”, and afterwards will add a marketplace with virtual currency.
