Been playing Starcraft 2 Legacy of the Void and found a pretty amusing coincidence (maybe it was planned?)
Each SC2 game released has you play the factions in the same order as the original game - Terran, Zerg, Protoss, yet at the end of LotV there's a three mission epilogue, where you play each faction in a different order, but it's the same order as the Brood War expansion...
