Best Games for Seniors over 90?

Hi HN, I haven't gamed for a long time and I need some advice. A friend's mother is over 90 and wants to try to some video games.

I have an Apple TV and my friend has an XBox. We are looking for simple, fun games that are not too complicated to learn. Multiplayer (in person with a second controller) would be great.

Just doing a quick search on the Apple TV, it's hard for me to figure out which games are compatible with an external controller. But the bigger problem is figuring out which games are "friendly" to the beginner.

Any advice? Thanks!
