Mage: The Awakening
The New World of Darkness version of Mage: The Ascension. They basically removed all the cool diverse traditions and organizations from the old one and substituted vague, indeterminate, inscrutable new ones. Much less emphasis on the the fate of the real world, now that mages get their own special spirit world to care about.
People hate it so much that they play it more than they did the old one, and people who barely ever played the old one but felt entitled to en endless, non-playing discussion circle jerk feel sad that the expertise they developed arguing about a particular imaginary world has been reduced to its actual, marginal social value.
