Between the modding community (thank you so much for your donated work), Steam, and Bethezda, they have made the platform fairly stable if the framerate mods and tweaks are used.
I think it would be a great platform at this point to host other stuff, maybe as dlc type plugins.
For example:
Fallout 3 that won't run in win10, ported for the fallout 4 platform.
Fallout New Vegas ported to run as a dlc.
Maybe use Nuka world type connectors for each gaming area?
