sunk cost fallacy

[Portia]

I highly recommend the chapter in Thinking, Fast and Slow, about sunk-cost fallacy. Cut your losses. But then, it sounds like you are an optimist by nature, and they are particularly susceptible to throwing good money after bad. (I'm an inveterate pessimist.)

I'm working on a blog post about videogames and this fallacy right now!
