Post what, in your opinion, never goes out of style, and is perfect for all ages. If you want to, give a quick explanation.
In my opinion, the Pokemon games never go out of style. I wouldn't be embarrassed to walk around playing Red, Blue, or Green version on a classic DS. It may be some sort of regression tactic now that I think about it, going back to playing something that I played when I was about 5. Ahhh the memories.
