Why does the PC gaming industry still use such deceptive pricing?

Battlefield 2042 is $60 right now. One of my friends on Steam plays Battlefield 2042 and I thought hey, that would be pretty cool to play with him. I'm sure it wouldn't be that much because that game came out a long time ago and was extremely poorly received and like, I'm sure it would be really easy to buy that game or get it now since it's been so long and again, very low reviews. The game is $60!! But when it goes on sale, it's like 8$, so 80% off. Truly unbelievable. Why do they do this? Like, they're basically trying to kill the game or something because no one in their right mind would pay $60 for this game, so 90% of the time when it's not on sale, no one buys it or wants to try it out... Also, lots of old games that are "on sale" constantly for like $5 and the base price is 40-60$, so it makes it seem like SUCH a good deal, when in reality, the value has just depreciated...

They never seem to lower the base cost of anything, making it deceptive. Is it really 80% off of a $60 game if no one in their right f*cking mind would pay that much for it ever?
