Actually, working on Gear Gals IS being done out of obligation, and that obligation is because I said so.
It's FAR more nuanced that this, and as usual I spent WAY too long trying to figure out how I wanted to write this, but GameosynchronousOrbit's message became the final ingredient to, somehow, turn feelings of "I have to kill myself to prove I'm not a terrible person" into "I have to finish Gear Gals to prove I'm not a terrible person."
And there are a number of reasons why it specifically has to be Gear Gals, some of which being "because I said so," "because it's the game I feel the most confident about finishing," and "because of that tarot card reading I had years ago."
