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

20 $, tabletop simulaotr, I thought I could convince some friends to play with but instead the game is there to gather dust in my steam library.
If we talk about the game itself, Diablo 3 10 $, it has a fantastic story, but I hate the gameplay I was the only one in my group to hate it, I almost felt sick playing with that view like LOL one, but on LOL I haven't the same problem... don't know why
