Once upon a time, a studio named Riot Games made a game called League of Legends, which was essentially a Warcraft III map given some slight adjustments and a new coat of paint to avoid copyright infringement. Now, that studio is very successful because LoL made roughly all of the money ever printed, and it’s suing another developer on the basis of that studio skipping the “slight adjustments and new coat of paint” phase of the plan.
You can check out a trailer for Mobile Legends below, and… well, that does look similar, but it’s really up to the courts whether it’s similar enough to shut down the operation. It’s developed by Shanghai Moontown Technology and has already been removed and re-submitted from Google Play under a slightly different name. Time will tell if the lawsuit moves forward or not.
