About three weeks ago, the multiplayer game Myth of Empires was released in early access on Steam, and has become really popular. It's a sandbox in the same spirit as Ark: Survival Evolved, but now there have been accusations that it may have taken a little more than the spirit from that game.
Steam has removed Myth of Empires from its store, and on the game's official website, developer Angela Game writes that they have been accused of copyright infringement, which they deny. They do not say who is behind the allegations, but Pcgamer reports that it is Studio Wildcard and Snail Games, which develop and release Ark: Survival Evolved, respectively.
They claim that Angela Games was founded by at least one former employee of Snail Games China, and that the person in question had access to Ark's source code. After noting that Myth of Empires had many similarities to Ark, Studio Wildcard examined the game's executable file, claiming to have found hundreds of common variables, classes, and function names.
It is worth bearing in mind that these are only accusations at this stage, and that we simply have to wait for the situation to be investigated before drawing any conclusions.
