You can buy musical instruments for that price software or hardware synthesisers, for example.

But that’s exactly the point, I’d rather pay double and triple for something I know I’ll use for hundreds of hours than 80€ for a game that will last me 12 to 30 hours (I only play offline story-based games).

Even if I considered game X, there are decades worth of games availabe for under 10€ that I would rather get now or buy a Humble Bundle while waiting for a sale.

The issue becomes of all publishers start to follow Nintendo’s model and not dropping the prices much.
