Partying is not a sane way to spend money, but it's fun. When we were young, we did not have a lot of money at all, so I thought, 'If I ever get rich, I'm not going to become one of those boring rich people who doesn't spend money.'
PC gaming has always been strong, and I see it surviving for quite a few more years. It will be around for at least as long as people use PCs.
Just make games for yourself and try to have a critical eye to what you do. If you genuinely like the game, there will be other people who like it as well.
'Minecraft' certainly became a huge hit, and people are telling me it's changed games. I never meant for it to do either. It's certainly flattering, and to gradually get thrust into some kind of public spotlight is interesting.
I guess people feel like they kind of know me. The game developer me, or the Twitter persona, that's Notch. It's a censored version. The real me is Markus.
