This has been a big disappointment for me as well. I was pretty active on the forum the year prior to the ATV4, and was really excited about the rumors and possibilities. Before joining MR, I frequented the MacLife forums, which have disappeared, but was an ATV fan back then too.
Before the launch of the ATV4, there were a lot of rumors claiming that Apple was making a "console killer", and that gaming was a big interest for Apple. As we all know now, this never materialized.
The reason for the lack of good gaming on the Apple TV can be blamed solely on Apple, and a lot of their decisions related to tvOS at launch. This killed any momentum that the ATV had to be a gaming device.
1. The requirement for apps to use the Siri remote.
- This was probably the biggest road block to over come.
- It basically made it too hard for Devos to bring quality games to the tvOS.
- Take any popular console game, and then try to envision a version that had to be used with the Siri Remote.
- There should have been a standardize Apple gaming controller similar to existing gaming controllers.
2. The use of the A8 chip.
- The A8 was already few generations old at the ATV4 launch.
- The A8 is underpowered for console quality games from at least the last 2 generations of consoles.
3. The app size limitation was set really low at the time of the tvOS launch.
- I believe it was 200MB, more could be downloadable content, but it puts a hurdle in an already uphill race.
- This makes it harder to port existing games that do not already have a 200MB.
4. The ATV gaming presentation at the ATV4 event.
- CrossyRoads was not the best choice in my opinion.
- There should have been a well know graphic intensive port to show the capabilities of the ATV4.
- This is a sad moment for Apple imo.
you have to make your game be able to work with the remote(this part may be out dated)
This was changed a while back, but the damage was already done.
