It's getting ridiculous. Especially since they make more money by selling for less, by making up for it in volume, as there is next to no unit cost associated with digital distribution. You are only paying for bandwidth and electricity per unit.
PC game prices drop pretty fast so waiting for a sale is rarely a bad decision...plus the game will have gotten multiple patches by then
as far as Dying Light 2, I'm leaning towards getting just the base game for the current sale price of $35.99...the 1st expansion/DLC doesn't look all that great if it's just an arena combat mode
