I played Borderlands with my brother online once. He was ahead of me but we wanted to have fun together so we tried to play together.
I was on a mission to get the best gun for my current level. He was kind enough to just drop a gun that was as good or better for my level than what I was seeking. I no longer had to do that quest.
In fact, he dropped all the best guns he had through all the levels. I no longer had to do any extra quests.
I quit the game. It was suddenly boring. It was the need for the next new thing that had been making it exciting, and now that was gone.
I think about that sometimes for rich people. Why does it never get boring?
I once made an app for Samsung watches for disc golf scorekeeping. It could accept any number of players, apply a handicap throughout the game so you could know exactly how you were doing vs your opponent with different handicaps on every hole, and gave a nice scorecard at the end to view. It was $0.99
Someone complained that I made them “throw away their money down the drain” since it didn’t also have gps to tell them how far they were from the hole.
