16-bit games were more expensive here, SNES games topping 200 guilders which is 90 ish euros. MD games were slightly lower, capping at 170 (75 euro) or so. We never bought many games back then. It wasn't possible. We would rent, borrow, trade, and buy an odd game used. Discounts weren't really there, only for some games. This was at a time when income was twice as low as its now, but cost of living was twice as low as well. Games were just extremely expensive. Consumers owned generally less games and you became good at those tough games since you had nothing else to play.
With discs however, this was reduced drastically. It was on PS1 that I started to buy much more games. RRP's were far lower than SNES, and discounts were more often as well. Used market also exploded, probably because of availability and consumers buying more games in general. I remember PS2 games also started at 70 euros, but eventually lowered. I think a price increase isn't that weird (PS3 and PS4 gen didn't increase for example which is like 15 years), but the timing is.
There is however more flexibility. There are games aiming for a lower RRP. But because this gen just started, they still try to sell certain games for a premium. Like Destruction Allstars, which wouldn't be worth it at all (I play it, and its absolutely not worth more than 20) and Sony quickly backpedaled. Returnal is another one I feel isn't worth it but we have to wait and see. If it doesn't sell then they will backpedal. FIFA, 2K, GTA however sell no matter the price.
