Sad is definitely the word. It's hard for me to believe that after a year, tvOS still has no games worth buying. I've tried a few, even dropped $50 on an excellent MFi controller. It sits there unused as there is simply nothing to play.
Yeah I also bought a nice controller. Part of the problem was that Apple really limited everything at first by requiring every game work with the basic remote. Hopefully the AT&T DirecTV Now Apple TV 4 bundle deal puts a lot more units out into the wild so that there are more people buying games.
There are a few games I consistently come back to but only play for like 5-15 minutes at a time. These include Mr Crab 2, AG Drive, Canabalt, Mr Jump, Crossy Road, Mikey Shorts, Badland, Ducktales, Riptide, Alto's Adventure, Oceanhorn, Surfingers, and Sonic. Many are older games I already owned that were ported, several are free, some are simple one-click games with a repetitive mechanic and some done well, and some are remasters from other consoles. Don't think any of them were over $5. I don't really see many decent games being developed specifically with the Apple TV in mind—it's just more of an afterthought. Minecraft is supposed to be coming soon, and that might give the platform some legitimacy and possibly boost sales as this would be one of the cheapest ways to get Minecraft up and running for your kids while getting all the other benefits of the device.
I was really hoping the Apple TV 4 would become a legitimate gaming platform with more quality, deeper content than what is found on the iPhone and iPad. I have two young kids and my oldest will be three soon and she is becoming interested in games, so I was hoping the ATV4 would have a lot of family friendly games. I'm starting to think that maybe the Nintendo Switch will fill that role, perhaps combined with the NES Classic as soon as I can find one. I was worried for a while that Nintendo was dying, but I think they might save it now, so I don't have to root for Apple to replace them in the family living room. And as always, daddy will have his Xbox One and later on, Xbox Scorpio downstairs in his office where he does his real gaming, lol. I don't think the Apple TV will ever compete at that level so I'm just not even going to hope.
