Taking inspiration from other games when making your own is pretty standard. That happens all the time, across all companies. Gameloft, the famous developer of mobile games, have built their entire business model on being inspired. And when building a brand new MMO for the iOS devices (Android yet to be confirmed), why not be inspired by World of Warcraft?
The name of Gameloft's new game is Order & Chaos Online and it's "coming soon." We've seen MMOs work on phones before - like in Pocket Legends - and Gameloft have a history of making good games. So will it work, or will it simply be another WoW clone? And with that we're talking actual clone, not just a game with similar features to WoW...
