Google charges 15% <$1million

Steam charges 20-30% depending on how big you are, and probably has a sweatheart deal with EA.

Xbox and Playstation offer subsidised hardware and arguably have a 0% rate given that so many titles are published in-house.

Nintendo offers an effective 25% rate as 5% of spend is rebated to customers' wallets.

Microsoft charges 12%

Epic charges 12%

Are the different rates reflected in the prices on the store or does the customer pay the same price irrespective of the cut taken by the platform?

The different rates are reflected in the burnout, low pay, bankruptcy and failure - or the opposite - of the developers who launch on them.

Right now for example its basically impossible to make a reliable income just from PC, for the average solo developer or micro-studio, due to the insanely high 30% commission taken by Steam.

Its necessary to launch cross-platform onto consoles, and optimizing the graphics and control schemes for these devices means that PC is not the focus.

Just because you don't like it, it should be forced to die? You know there are people happy with the way it is...
