"Violation of copyright laws and trademark laws" are at the forefront of Blizzard's suit against the mobile developer.
I kind of saw this one coming. I recently previewed an upcoming mobile game called Allstar Heroes, and you can read my preview over here. One of the problems I found with the game was its lack of originality when it came to character design. Most of the characters I encountered were direct copies of Dota 2 or Warcraft 3 characters, aesthetically, and with their in-game abilities. And now Warcraft 3 developers, Blizzard, have filed a lawsuit against the publishers of Allstar Heroes.
Gamasutra spotted this press release on Blizzard's Taiwanese website, which they translated using Google Translate. It states that Blizzard are suing Lilith Games, developers of Soul Clash, know as DOTA Legend in Taiwan, and now known as Allstar Heroes in the west. Blizzard say they're suing for "violation of copyright laws and trademark laws."
What makes this story even more interesting is the fact that Lilith Games are also suing uCool, the developers of a game called Heroes Charge, saying that the aforementioned mobile game is a direct copy of Soul Clash.
Lilith Games CEO Xinwen Wang said the following in a statement regarding the matter: "Heroes Charge is so identical to Soul Clash in the rules, the character set, and even the user interface that we assume it could have been created by decompiling the source code of our original game."
Heroes Charge has been rather successful for uCool, ranking highly on the iOS app store and also having its very own Superbowl advert during this year's event, which cost $2.25 million.
