Whats the best Linux distro for game making and internet browsing?

Whatever you want, really.

When the question starts with "what's the best Linux distro…" there is a slim chance that you can go wrong with saying arch (or derivative). At least that's what I believe. Though if you are starting you are probably better off with Mint or Ubuntu.

Honestly Windows since almost all players of your game will use it. If it absolutely has to be Linux check wich distro is recommend by the engine you're using.

@crafter I intend to use the Unity engine but Im not sure what distro I should use
