Slightly old thread I know, but wanted to chime in momentarily:
$30 can be expensive, if you aren’t a game dev professional, don’t have time for your projects 24/7 ISH, etc. That could add up kinda fast, whereas at least with UE4 you can take your time as needed, and pay in the end when its solid. Thats a big deal to many indies. Maybe Autodesk will come up with something similar who knows, and I can already think of something that would be fair at least to studios who have great ideas,but small teams and far from huge expense budgets.
