Yeah the sales suck. I almost feel like adding anything to your wishlist is working against us. If 95% of the Steam populate adds oh I don't know, Cyberpunk 2077 to their wishlist, THEY KNOW. That means either, let's never throw it on sale for a long time, OR, let's just throw in a 5% discount on it to see if we can entice any of those 95% to buy it with a measly 5% discount.
Wishlists seriously allow them to probably decide how much and when to discount games based on research. Do players that had it wishlisted buy it for a small discount? For a large discount? For no discount? As they compile the numbers, it gives them their plans of how to discount future games. I think it was Amazon who said it best, like once they have the data (of the people shopping with them), they can control everything, lol.
I ended up picking up "people playground" for like 1 dollar, lol. Of all the things on my Wishlist, it's the last thing I expected to buy. Though yeah, the rest of the sales suck so I'll wait.
