They do and they have by far the most unstable fanbase of the big three.

Supply and demand and because Nintendo gamers are collectors.

PS4/ONE there is a huge second hand market of games being sold cheap so publishers have to slash to get sales.

Nintendo gamers keep their games so no option but to pay full wack i you want to own it.

It seems to depend on the game as well. Odyssey and BOTW have dropped very little, but other games drop 10-20€ relatively fast, at least around here.
Xenoblade Chronicles 2 for example is down to around 40€ by now. Sure that is not in selcets range, but it's usually not true that Nintendo games don't drop at all. It just takes Nintendo significantly longer to bring out selects versions of their games with an official price drop, then it takes other companies to come out with a GOTY version.

All of that is part of why their war-chest is as big as it is. Their development budgets tend to be modest, compared to the typical AAA budget, so they usually make development cost back rather quickly and then rely on legs to really fill their pockets. They tend to value their games high and it works because most of them have fantastic legs and retain good aftermarket value. It's smart businesswise, but as a consumer, obviously I tend to hunt for deals.

My pet peeve is the pricing for the likes of DKTP though, it's a barely retouched game that is 10€ more expensive than it's original and as much as I love the game, and would love to play it portably, Switch 'remaster' pricing really screws over WiiU owners, so I'm holding off for now.

I tend to buy my games from amazon.fr or amazon.co.uk now, since amazon.de has insane markups on nintendos first party games. BOTW is still 69€ for the standart version for example, more expensive than any other european country from what I can tell. Other retailers seem to go either with 65€ or with the actual 60€ for new games. BOTW goes fro 50-55€ on other german retailers currently. I'm not sure what is happening there but amazon.de has consistently been going over msrp with Switch games.

Your point was that Nintendo games continue selling so they don't need a price cut. So surely games like Arms, 1,2 Switch, Xenoblade, Bayonetta etc should be in for a price cut since they're not charting high? For Nintendo its not a case of selling versus not selling otherwise half of their games will be on discount and most games that are discounted om PS4 are already selling much more than Nintendo's mid-tier titles (i.e games not MK, Zelda..)

Nintendo is the apple of gaming. *shrugs

Eventually, the gravy train will end when there's not enough fans to sustain it. Nintendo will either adapt to what gamers want or they'll be segad.

You can buy Zelda now and then Arms later. Problem solved. These sales do not exclude each other unless your entire budget lasts only one game.

Gamers have unrealistic expectations. They want everything in best quality with all kinds of stuff packed in and all shiny shiny - but pay next to nothing for it.

It's been what? 35 years since the NES and they've been surviving and thriving since. Clearly the majority of the market don't care as they find the games are still worth their value after more than six months. They can still top the charts at that price, while even most heavily discounted games struggle to keep up with those kind of legs. Even Mario Kart Wii is at the 69th spot on Amazon 2018 video game best sellers list at $35. People are happy to pay for a quality game.

Also Nintendo Selects exists for the very purpose of forever lowering a 1st party's games price to around $19.99. Switch has just only been out barely longer than a year, most of it's big titles aren't even a year old yet.

That's fine.
And it's all well and good to list prices for US, Canada, UK and so on... But... That's still not Australia. Haha

EB Games is currently having a half price sale on, so it's currently at $50 AUD, but when that ends it will jump back up to $100 AUD.
I just think it's nuts. But it is what it is.

this is why its good to have options.
