Just had a realization re: #gamedev. Especially as I get older w/a wonderful family, I have less time for games. Getting on and playing at same time with friends is near impossible.
BUT! (and MMOs have this) the ability to multiplay async is possible. Crafting and sending items to help your friends, etc. (Note: I am not talking about turns sitting in a notification somewhere.)
Designing a game with lots of ways players can async play together is a critical element.
@timotheus The original Gamecube Animal Crossing did this in an incredible low-tech way: http://animalcrossing.wikia.com/wiki/Item_codes_(GCN) in-game it would say "sending thing to your friend, give them this code" but there was of course no networking, it was just a hardcoded hash. Clearly abusable, not for competitive play, but I always thought that was really clever.
