I broke this habit once growing when I decided to finish Mario and Luigi Partners in Time after a break. I had just reached the final dungeon, but before diving in I realized I had more money than I knew what to do with.

I went to the store, got like 99 of all the cool looking items, entered the dungeon, and went to town. Every turn was a question of whether to use a power flower, hammer, or what have you. I mowed through all those end game enemies and the final boss didn’t know what hit em. It was glorious.
