It's not amazing. Companies used microtransactions to keep the retail price low. The price of most complete games hasn't been $60 since the 2000s. People are just happy with the, "I bought the game for $60 and I can skip the DLC," argument. But if anyone wants the entire game, the math is:

Complete game price = Base game + (DLC + Season Pass + Pre-order bonuses + "Partnered Sponsorship" tie-in codes + subscription models + optional microtransactions)

Not all of it applies to every game, but most, [not all], games have something in the parentheses of that formula.

And companies like Square Enix try to use the entire formula. I'm pretty sure the only thing Final Fantasy 15 didn't have was the subscription. They had multiple DLCs for that game that required buying other products to get a code for a weapon or armor or something. (－_ლ)
