I disagree - I use mine all the time to play RimWorld and Minecraft on my TV in the living room. For Minecraft in particular it's nice to be able to use my gaming PC in my office to play in the living room, because my kids are on the couch on their laptops participating in the same world.

Latency is the big issue, so FPS games are right out. Once you realize that, then you can choose the games you play with it to fit the platform.
