Sure, Gems is up there for obnoxious MMO minigames, but for me? It’s Polymock.
I had almost forgotten Polymock existed until a WoodenPotatoes video put it back in my field of vision. It was a minigame in Guild Wars 1 that somehow managed to be excruciatingly frustrating and unnecessarily latency-based as well as tied into the game’s valuable faction system. I remember playing it before everyone had figured out the optimal way to win, and by the time the strats were common knowledge, I just wanted to throw all my virtual Polymock pieces across the room and get back to playing the great MMO I’d actually signed up for.
What do you say is the worst minigame in an MMORPG?
