Comment I learned how to manage people while playing DAOC (Score 2) 25
DAOC (Dark Age of Camelot) was a MMO back in the 2000's similar to World of Warcraft. I was in a top PvP guild on the Palomides server called Insurrection. Insurrection was only ~12 people and to properly farm for the good end game items it was necessary to link up with the other top guilds on the server. I routinely ran dragon / dungeon raids of 40-60 and learned how to coordinate large groups of people toward a set of goals and then divide the spoils (as well as keep those who didn't get loot interested in the next raids).
I used that skillset to start to manage small teams at startups, then larger teams, and finally I was running 200-500 people across several teams @ Zynga during its heyday.
