I want a game that actually reinforces the social fabric instead of simulates it. Something that encourages people to be together in the physical world (gasp!), have fun, have shared experiences/goals/challenges, and form lasting friendships.
I have very fond memories of lugging my computer (and CRT!) to my friends/family's house to have a LAN + pizza party. The best part for me wasn't necessarily the game itself. The games were fun but I really enjoyed the social aspect of talking about a tough dungeon or strategizing how to beat a challenging opponent.
It seems like the industry is trying its best to bring people into a simulated world but why not use games to bring people together into it instead?
Pokemon Go is probably the closest thing to this I've seen recently but the core gameplay was unfortunately pretty boring when it first started and became popular.
