I've been revisiting the game Age of Empires with my friends while keeping at home. Today I learned that even that part of the game mechanic stems from some research!

It's a great game for an online social event, because you have to commit to the 2+ hours it is going to take to play. A lot of online games nowadays are optimized from dropping in and out amongst a pool of random people, but AoE makes you do the work to get people involved and stick to that commitment.
