While servers for WoW Classic are under siege from scores of players, Blizzard is gearing up for another war with Sina Games – creator of the mobile game Glorious Saga.

A lawsuit has been filed against the Chinese developer for a "massive infringement" on Blizzard's IP.

Even the briefest of glances at Glorious Saga will spot infringing assets, with Blizzard claiming that "every monster, creature, animal, and vehicle in the Infringing Game was copied from the Warcraft games."

"Weapons, amulets, and other objects were taken straight from the Warcraft games, without pretense," the suit alleges. "Audio cues and sound effects from the Warcraft games were reproduced for the Infringing Game."

If you're one to offer Sina Games the benefit of the doubt, it should also be pointed out that Glorious Saga includes characters like Jaina Proudmoore, Gul'dan, and Malfurion.

Blizzard is seeking maximum damages of USD$150,000 per infringement, plus legal fees, and a permanent injunction against all Sina Games titles that infringe on Blizzard's properties.

In response to the lawsuit, Sina Games has taken the game down, posting on its Facebook page:

"Thanks for your support and love of our game. We had a great and happy time in the game.

"But due to some irresistible reasons, we decided to announce that the game will stop operating at 06:00 on 29th of Aug. (EDT), and all the servers will be closed. Players can't login any longer."

Yup, lawsuits are pretty irresistible.
