Recommendations: Selling Out to Joja
Selling out to Joja is a lot more fun than most people make it out to be, and definitely not the soul death some redditors would have you believe. After all, is it really better to exploit junimos to fix up the town in ways that benefit you personally in exchange for resources they don't seem to have a use for? And when you go blue, you don't have to worry about finding that elusive red cabbage. What's not to like?
Well, for one there's not a lot of content original to Joja in the Vanilla game. In fact, the NPCs don't even notice Joja fixing up the town. Fortunately, there are mods that make selling out both fun and profitable. :D
