This may not be an appropriate question for gamedev.stackexchange.com.
I'd like to make a basic Breakout game with Unity.
I'd also like to sell it on the Mac App Store, iOS App Store, Google's Play Store, Windows 8 Store etc.
I'm not sure however if that will cause trouble with Copyright.
I asked Google but I didn't find any helpful results.
Can I use the game-concept without buying a license?
I know that there are plenty of games with the same concept on various platforms, I just want to be certain.
