LTSC won't work for all new games or games that receive and require updates; I recently spoke to a game & graphics dev with a lot of low level DirectX and Windows API experience about using LTSC for a flight simulator (not just the software - a simulator you physically sit in). He said that he had to deny support for LTSC for his products in that space because MSFT doesn't update it with the same DirectX updates and Windows APIs available on consumer Windows versions, which in turn impacts graphics driver support, which in turn prevented features of his software from working at all on common hardware (in his case, VR/AR displays). The same issues will likely impact many games that require newer graphics APIs and drivers. He advised against LTSC for most gamers - it's only appropriate for running software that was built for the SDK and API versions available in LTSC, and which won't receive any major update for a decade.
