A game being good is a matter of opinion. CSGO is one of the most popular games in the world and you can buy guns to use for one match. CoD is another game that sells guns at times, the best gun in one of its games was cash only. Just because you don't want it to work doesn't mean it doesn't. If you think people are dumb for spending money how they want to that's a you issue. You should really worry about your own finances.
