While I think it might be a bit caricatural to reduce the situation to microtransactions and NFTs, it is indeed true that large studios are turning towards more profitable business models, and with 52% of last year's global consumer spending on gaming in 2021, mobile gaming is the new king in town. It's now bigger than PC and console gaming combined, and microtransactions are the essence of its business model.
Rayman Legends, apparently the
best-selling Rayman videogame with 4.48 million copies across all formats, as of 4 February 2019, which we can estimate to have grossed $224M at $50 a copy (probably less), is completely dwarfed by the giants of today's mobile gaming industry in terms of the revenue, and it's easy to imagine that all major publishers are looking to replicate the success of Honor of Kings/Arena of Valor ($13B+ revenue since 2015) rather than come up with the latest groundbreaking platformer that will barely cover its own development costs.
