The game you chose is on sale for $5.99 and You went on a rant about over-priced nostalgia, choosing quite possible the worst example to justify your point.

That game is known in the gaming industry as the series most popular installment - so naturally, they’ll bring it back for fandom and nostalgia. Yeah pretty surprising that game developers need to make money too, why would anyone need to get paid for hours of programming pixels? How dare they capitalize on a successful product of theirs? They should be giving away their IP for free, they don’t have families too.

At that price point, I don’t see how you could argue greed as a variable. It’s the price of a cup of coffee.
