You're mistaken about daz pricing.  I get most of my assets for about 80% or more off and then pay between $10 and $25 for licensing.  Since that's almost always in a pack I am usually getting several outfits for the price of a single item with an extended license on from your store.   For my use, it's at least $50 to buy a single shirt or piece of clothing.  That's a price of $150 for a 3 piece outfit to buy from you.  I can get 6 to 9 (or sometimes more) complete outfits from DAZ for that price.  There are some complications with using daz items but dealing with them is well worth the cost savings.  I can get a quality complete custom outfit off fiverr for $150.  Seems wild to me that content licensing is so restrictive.  I've literally never seen anything like this.  I can not think of anybody else who has such a restrictive license.  It's obviously meant for a very specific use case.  And video games isn't that case.

Most of them were developed by professional teams with dozens of 3D modelers.  There are also many games that use DAZ assets.  If I could afford dozens of 3D modelers I would hardly care if I had to spend a couple hundred dollars on an outfit.

I have spent thousands of dollars on both Reallusion and Daz stuff. Reallusion has extended license which is around 1.xx to 3x that of standard pricing. Daz is $10 / $35 / $50 extra (depending on type of assets) for their "Interactive License", the equivalent of Reallusion's extended license. However, not all Daz sellers offer "Interactive Licenses" even if you want to buy one and if you want to use them in games, you need that interactive license. All price quoted are before discount.

But in the long run, Daz is offering much cheaper price because their discounts combos are insane, and they have way much more asset creators over there. Most of the stuff I bought from Reallusion are the core software and plugins, hairs, some clothing assets that are not available in Daz, and those super amazing motion packs. The rest are all Daz. Need to mix and match to get the best of both worlds...

NOTE: Yeah. Reallusion licenses are one of the most restrictive ones around. Need to contact them to buy an additional Enterprise license on top of standard/extended license if you want to use that in a game that allows players to change clothing etc that are bought in Reallusion or customize CC4 characters in-game, just like those typical RPG games. Not that indie friendly...
