I think you should become more aware of your expenses.
If you wanna stick to Blizzard examples: forgot how much people were pissed off when it was announced that Diablo III would be 60 dollar/Euro straight? WoD was the first WoW expansion that cost 45 dollars, as opposed to the usual 30. Both is pretty much the norm now, and it's just a case of the industry looking at what they can get away with.
Contrary to your memory, I've been buying new PC titles for around 45€ for over a decade. The leap to 60 is relatively recent. Not buying the inflation argument either - were talking about 20-30% here, well that's some Uganda-worthy hell of an inflation!
