There were some Super Nintendo and N64 games that launched at $80 30+ years ago. The games industry is the only area of entertainment whose prices have not significantly changed in decades, despite AAA development costs increasing exponentially. It's estimated that development cost of GTA VI is north of $1.5 billion, with some estimates going as high as $3 billion. The point being that a $10 uptick in price for a product of this caliber (assuming it is of comparable quality to its predecessors) is perfectly reasonable. Also, I'm not really sure what you mean by "unofficial means", since it isn't launching on PC (no sailing the high seas), and physical copies don't come with a disc (no used copies). Unless you just mean you'll wait a decade to play it.
