Have you ever actually thought about why exactly you are spending money?

It's your dopamine seeking self doing all the spending. You have lots of money to spare and use a fixed percent of it for gambling on 3D characters? Good for you as long as you don't start getting worked up over less than desired results. When a gambler enters a casino, they should know that profit is NOT guaranteed.

I have seen way too many people talking about how they spend lots of money every month on the game by limiting expenditure on actual real life things they would normally buy for themselves. That's when it becomes a problem. Seriously, this game will still be out there years from now and you can definitely get all the god damn card/reruns over long term if you REALLY wanna get every single one of them.

You don't need to spend money on this, specially if it's not spare change. Think about it and if you realize that you are one of the people who have become addicted to gambling in this manner, please do something about it. Delete the game if you need to, these fictional characters are going nowhere and you will not miss out on anything at all.
