First, I'm getting bored of telling you: we already know Gentoo isn't for everyone, it was stated by the first user talking about it, in its second post.
Second, game programming doesn't require huge resources, you just need to be able to run the IDE and the game.
Third, nobody says you should switch, you already stated your priorities, and everyone is respecting them. You should learn to respect other people's. I have some old machines, and I might want to turn them into basic workstations, and no current Windows can help me for that. I don't have money to buy hardware, and even if I had, I might just like to do experiments. Nobody forces you to use them.
