Thanks for writing this. I got out of the game industry myself after working as a developer on 8 games in a row that failed to make hardly any money at all, for three different companies (two startups, one small business).
I've been working on corporate software for 3 years now, and while my finances are back on track, it's gotten harder and harder to stay motivated and I've been really tempted to take another stab at it, despite not really having enough saved up to do so (especially if my girlfriend and I are going to buy a house this year).
Anyway, it's tough to just sit and stare at the die and not roll it. I have done some board game design as a hobby, since that doesn't totally drain me like extra programming does, and I've even gotten my first publishing offer recently, but I know firsthand from other designers of successful titles that the money you can expect from it is minuscule compared to making a successful video game (one person told me he made $10k in royalties off a game that you can buy at Barnes and Noble. I've made more than that off a video game that was only somewhat successful).
Anyway, I've played and enjoyed A Dark Room. I should probably check out your other games. Thanks for taking the time to share your story, it's given me something to think about.
