I just made this decision about 5 minutes ago, so I'm posting it here as some form of commitment to stick to it.

A while ago, I decided to make a Minecraft adventure map. An embarrassing amount of time was invested into making it, but sizable progress was made in that time. That's what kept me going. The feeling of making progress on a big personal project.

But taking an outside view on it...

How much time will it take to complete? A whole hell of a lot more.

What could I do in that time instead? Make more friends, learn a programming language or two, plenty of stuff.

What will probably happen if it is completed? I will probably get a few dozen downloads of the map and that's it.

What benefits will accrue by completing it? Not enough to justify the time spent on it.

Somebody is calling this project an example of the Sunk Cost Fallacy. How would I respond? Hang my head in shame.

Is it fun? Somewhat, but much more fun things could probably be done with the time instead.

So I give up. It's a really huge sunk cost by this point, and it feels terrible that I used so much time on something I just abandoned halfway through, but every time I imagine what someone smarter than me would say, it is some variant of "Finally you realize it now." Time to walk away from Minecraft, permanently.
