Youre a games developer irrelevant of size its a way to monetize your product
How?
Theres nothing that ionomy can offer that offers a clear path to monetisation, so I think youre just playing buzzword bingo here.
However which way you want. From a big publisher like EA to a small indie developer it's whatever best fits your product.
An example
Played Fifa 20. You buy a player pack. In it is a rare ICON card like Pele 1958 World Cup winner. Currently, the Entire economy is centralised. Now the entire economy is able to transition to the ION block-chain which if your EA means the cost of maintaining the economy is significantly reduced and if your the gamer that bought the pack they now own an asset on-chain which gives the dev a lot more flexibility in its consumer offering.
Now if you're a small Indie developer...

For an Indie developer, it's not just about plugging into an economic infrastructure.

The limiting factor is your imagination
