Pokemon GOhasmade over a billion dollars, giving players a new way to use the augmented reality (AR) technology in their smartphones. The game’s success means that many similar AR games have been made, but it seems thatPokemon GOdeveloper Niantic isn’t best pleased about the latest rival release.

In an email statement sent out to press this week, Eyland, the developer of AR gameDraconius GO, alleges that Niantic has filed a complaint against its game. Eyland claims that “We’ve received an un-grounded complaint from Niantic in the Appstore — they think we’ve violated their copyright.”

Draconius GO Pokemon GO rival game

Eyland says that when it began developingDraconius GO, which allows players to go out in the world to catch and collect mythical characters, it consulted “leading world-class lawyers”. Although some screenshots ofDraconius GOdo seem to have a similar style toPokemon GO, Eyland stresses that its game is “absolutely original”.

Eyland says it didn’t use any of Niantic’s “coding or graphics when developing [the] product” and is “100% certain that Niantic’s claim is unjustified”. The developer also suggests that Niantic has only filed the complaint because it seesDraconius GOas a “serious rival”.

Draconius GO’s collectible creatures - which include dragons, unicorns, and vampires - may not have the charm of characters such as Pikachu and Mewtwo. But what Eyland’s game does have, is better support for rural players and many of the game’s 100,000 players cite this as a major factor for playing. It has ‘Pillars’ (its version of Pokestops) every 200 meters, meaning that rural players can still enjoy the game despite not being near many points of interest.

Although Niantic has vowed to improve things for ruralPokemon GOplayers, those who live outside of urban hubs still say that the game is less enjoyable for them. Recently, players complained that manyruralPokemon GOPokestops had been removedfrom the game, leaving them with no in-game locations for miles around.

Moreover,Draconius GOhas player versus player (PvP) gameplay. Niantic has promised to addPvP toPokemon GO’soon’but as fans are still waiting this provides just one more reason for people to play its rival instead.

It’s unclear whether Niantic may file additional complaints on top of this alleged warning, or what other action the developer may take. There are plenty of otherPokemon GO-likes, such asGarfield GOand theSharknadoAR game, and it will be interesting to see whether they receive complaints from Niantic too.
