Good video games borrow; great video games steal, and Activision-Blizzard’s World of Warcraft is a great video game. Since launch, WoW has systematically added features originating from outside Blizzard's internal talent pool. Whether integrating UI improvements ganked from the massive WoW modding community, or lifting gameplay features straight from competing MMOs or games in other genres, WoW is very good at recognizing what works and bringing it to Azeroth.
Blizzard Entertainment has announced the opening of beta registrations for “World of Warcraft: The War Within,” inviting players to explore new subterranean worlds beneath Azeroth.
Danish from eXputer: "Despite Blizzard's attempt to give a fresh new spin to World of Warcraft, some fans still seem to be stuck in the past."
HG writes: "Blizzard is usually pretty bad at keeping secrets, but the company somehow managed to keep this one under wraps until now. Plunderstorm is a special limited-time event that’s basically World of Warcraft’s take on the Battle Royale genre."
Great article :) Although FFXIV is one MMO that did not take good things from others and implemented them. They could have avoided a lot of criticism if they would've done that.
