Dear Gwenn,
I don’t want force anybody to use this OS or another. I just wanted to explain all the stuff on any example. I know oS very well, so I can only use it as an example. No, use Mint, use Ubuntu, use any distro you like. The problem is other: we should say people clearly that most things changed in the Linux world. Linux can be a very good platform for game developing, maybe not for playing, but just for developing.
