It's a great idea !

Developpers will be able to publish titles if they are good , easily wihtout needing to seek for a publisher !
And it's said 80% of income will go to the developper !
A good way to make Unity even more popular !

Selling Assets , is an idea already done in Torque 3D or Dark Basic pro site.
For FPS craetor they also put a store to directly purchase
any model needed for making a game !
I find it a really good idea, if the models and model Packs will be quality !

A8 could also make that , it would only boost A8 visual quality games i think !
Some coder, buying a quality level pack, would make a game
tat at least would have a visual attractive level
