WINE is Windows APIs running on the Linux kernel ( host OS kernel ). The Linux kernel is already high quality and high performance.
ReactOS is Windows APIs running on the from-scratch ReactOS kernel that is not very good.
The ReactOS project is not the source for most of the APIs a game is going to use. Many of the come from WINE.
Using ReactOS instead of WINE on Linux makes little sense at this point. It would certainly be a lot more expense and time to create a commercial quality product. Most of the work creating API support to WINE / Proton is portable to ReactOS of the kernel ever gets there.
