After many years of working, I have the time and resources to pursue one of my side projects full time for a few years, an indie MMORPG as a sole developer. https://alpha.reconquer.online
I'm a good software engineer so I wanted to create something more framework based than just level design so there wouldn't be as much competition. I also felt like I was wasting my life working on other people's projects.
The company I worked for folded, I had a very young child, and the job market was disastrous in my area at the time.
That put me squarely in a "nothing to lose" place, which took the risk out of starting a business. So I did, teaming up with the president of the company that closed. That business was a modest success: it didn't make me wealthy, but it did eventually provide enough income to support my family and to allow me to bankroll my next business. It was off to the races after that.
