While this is stereotypically true, my grandparents that passed away 14 years ago were avid gamers. They adored their NES and bought a SNES when the NES died. I think it is worth inquiring with local nursing homes to see if they have anyone that has gaming experience. My grandma’s favorite game was Loopz. Grandpa’s was golf. Puzzle games especially are good for that age group as they keep the brain busy but don’t necessarily require adept fine motor speed like other genres.
