Yeah I also see this as a positive development. I don’t buy into the FUD about app stores that is discredited by none of it happening on Android. On the other hand, if this is what it takes for Microsoft to port their expanding game empire to iOS, then it could make iOS a viable gaming platform. Which in turn would both encourage other companies to start porting their games, and likely spillover into macOS, even if just via the existing iOS compatibility system on Apple-silicon Macs.
