My brother in-law(the younger one, he's maybe 12), He has all the Pokemon games after Diamond and Pearl. I keep my updates from him. I personally liked it cause if I was bored, I can just grind and level up Pokemon. It's fun to me, I'm not sure what your likes in gaming are. You start with nothing, a Professor gives you 3 options of Pokemon to choose from, a Water, Fire or Grass type. You choose one, you have a rival and you fight them basically thru the entire game battles here and there. Collect the Gym badges from 8 Gym's on your way to the Elite 4. Capture normal, rare, legendary Pokemon on the way as well.
Also there is always a bad guy out there, like Team Rocket, or in the case of Omega Ruby and Alpha Sapphire, Team Magma and Team Aqua.
