I have an example, most of DCS World’s content is made by external people, each “mod” that adds a new aircraft priced at full game price, and is actually worth the money.

Bohemia is trying to do something similar to Arma, with some community mods being sold as essentially DLCs.

I can’t say I don’t like the model, if the content is big enough. No microtransaction crap though like the first iteration of paid Skyrim mods. Those sucked.
