I am developing a little mobile MMORPG which is Google Maps based and uses your GPS position to make you play around your area.

I came up with the idea after a famous and beloved game called "Parallel Kingdom" shut down their servers two years ago. It was a game with a huge playerbase and they had basically exact the same game concept. You played on the Google Map, could fight different monsters, meet other players, level up your equipment and co. So basically I am using the same idea, and many of my content is based on "Parallel Kingdoms".

Now I asked my self: am I allowed to do that? To use the exact game concept?

I researched a bit and found following on their website:

So what am I allowed to do and what now? Is it ok to copy the game concept and even with mostly similar content like "fighting", "building houses" etc.? I'm completly unsure about this because my simple English skills don't really understand that law slang.

I should also mention that pretty much my whole user interface is based on the user interface from "Parallel Kingdoms". I didn't use any of their assets or code. I just use the same structure, as you can see in the pictures below.

Heres the original menu from "Parallel Kingdom":

Here's what I created for my game:

Yes, but ...

Is copyright violation.

  • Ok thanks for letting me know ! So you can basically protect a certain UI structure ( like the menu-grid representation ) by copyright ? If so how much would i need to change the UI ? Is it enough when i move the buttons or change the order of them ? I thought using different icons would be enough ^^ – genaray Jan 4 at 11:18
  • @genaray The exact limits are up to the jury. – D M Jan 4 at 12:17
  • @genaray "How much would I need to change the UI" - no one on here can tell you that; if you need to know you should ask a lawyer for advice on your specific case. – Brandin Jan 8 at 12:38
