The amount of discounts and severity of said discounts turns what is a 20-60 dollar game into a 2-10 dollar game, and valve has been doing this constantly. I’m not complaining, because I get more games for less like you could back in 1970, but it’s almost concerning how much Valve is doing this.
The games that get reduced that heavily generally are years post release. Without those sales, they probably wouldnt sell at all anymore. I doubt that this is negative business for valve
