Well, if it helps, Licho (developer), I stopped playing other video games sooner, because they were much more boring. Now upvote me :-)
I'm getting near 30. Most I know stopped playing much sooner, in about 20.
Firepluk I admit I'm curious how you going to end up in 5-10 years, if you PM me email I will put myself reminder for 2021 to ask.
