I nominate Perfect World International.
This game is the definition of pay to win. The makers of this game have perfected the art of microtransactions. There are people who literally sink thousands of dollars into this “free-to-play” MMO, and its so hard to do anything without buying from the cash shop that most people end up paying more for “optional” items than it would cost to just play WoW. Skill is no longer required to play, except for the skill of reading your credit card. The in-game economy is also now broken beyond repair and no one seems to care. They just stand around buying items to do nothing with. It is literally the digital version of feeding your cash into a shredder. It makes me weep for humanity.
What do you think is the trollingest game ever?
