Do you regret how much money you've spent on games or in game items/currency?

I've never been one to spend a lot of money on games and stuff, but there was one time that I spent money on the golfing game Pangya. It's a great game and I don't mind supporting the developer, but I do regret spending money on a Gacha format.

(Gacha games are when you spend money for a "chance" at getting something of a certain rarity, etc).
