I'm late 30s and will still load up MC before resorting to TV or other entertainment. Have played consistently since the alpha. I have a Realm going with a fair few adult friends where we just play around in a long-term survival game together.

None of us can commit the time we used to commit to games (a few of us have kids), but I reckon we each probably put in half hour to an hour every day or 2, and the occasional 2-3 hour session per week while doing work on another screen or on hold on the phone.
