Reddit user Khemist49 made quite the find after purchasing a box of Blizzard stuff from eBay. Inside, he discovered a disc containing the original source code for Starcraft. After a heavy debate on what to do with the disc, he ended up returning it to Blizzard. He initially received a copy of Overwatch and $250 of Blizzard cash for his trouble. Later, Blizzard reached out and invited him to BlizzCon with all expenses paid. They also sent him a big box of Overwatch and Diablo swag. One good deed goes a long way!
