There no doubt about that. Just like to point out that the quality specially, is determined by resources, meaning continuous support. Expecting a superb high quality product from a 1 time payment is a derailed illusion.
It’s what the store needs. Support from both sides, not just pamper the Devs to make Games and give the all assets for free. Artists need continued support as well, but Tim Sweeney is a programmer so of course he’s gonna pick their side.
If you look at the current state with Studios: They don’t want to hire people, they don’t want to pay for Assets, they just want everything Free while they charge mostly expired goods on Kids (In app purchases)… it is greedy. They need to share the profits, so that content (assets) is more price accessible and higher quality.
