They are,
I would love to play those games, but I honestly thought these games would sell 20 bucks by now,this is all due to my backlog really.
for example the next game I might get is captain toad, I think I saw a sell for 20 bucks the other day.
just waiting to finish bloodborne.
If you saw it sell for $20, that was due to a sale. That is not the typical price for Captain Toad. It's $40. That's what it was at launch and what it will continue to be for many years.
It sounds like what you dislike most about the Wii U is the fact the game prices on Nintendo games do not drop. This has been a known thing with Nintendo consoles dating back to what... the NES? I can't even remember an era that had game prices go through crazy drops UNLESS Nintendo overshipped a game really bad - like they did with Spirit Tracks in Japan where it was in discount bins two weeks later because of how badly the game was overshipped.
This sounds like your regret is that you didn't research the product and the softwre before you bought the console. You bought a Wii U without looking at the prices of the games you wanted first? Really? Hard to miss.
Nintendo charges what they do because they don't believe or approve of the industry trend to release games and basically make all your money the first month, then heavily discount the game and release game of the year versions down the road for $10 less than the original game costs to make more money again on what they advertise as a "budget" version, because it's more expensive to buy the old game and the DLC separately.
Nintendo believes in the value of continuous sales - releasing games that are going to not just sell the first month, but the first year, and maybe for many more. THey don't annualize any of their franchises, allowing them to maintain this price model. Is call of duty Advanced Warfare going to see price drops? Of course - it has a new game coming out a year later. THey have to rapidly discount to maintain sales heading into the new game release. Meanwhile, when Zelda U hits, we won't be getting a brand new Zelda title on home consoels for another 4 or 5 years. So they ahve no reason to discount it. SS will see a $10 or more drop when Zelda U releases, assuming that Skyward Sword is still in print, which it might not be. Still, stores that still ahve new copies will lower the price when the new game hits.
Essentially, Nintendo doesn't agree that the value of the software degrades just because it was released years ago compared to releasing today. They believe it degrades when a new version of said software comes into existence or if, unfortunately, sales of those games become so low it's either stop printing them or attempt to drop the price. If you recall, the Wii era did that with Nintendo Select titles - basically best selling titles that were no longer selling rereleased in a specially marked box for $20. Even then, it is rare Nintendo does that and there was nothing different about those games compared to the original release.
Hard to complain as a consumer, because the entire reason we get upset is because of what the rest of the industry is training us to think, and as a consumer I hate that they are training us to degrade software so fast. I'd much rather have software maintain it's usual value and then have sales to associate with it. Sales don't mean much when the software itself just continues to tank in price every month.
Nintendo frequently offers sales on the digital versions of their games on the Wii U (literally new sales each week), and they are releasing Wii games for cheaper as digital downloads versus physical versions.
This is in addition to frequent retailer sales. Target runs a buy one get one half off sale on Wii U games seemingly every 6 months, and Best Buy among other places run some nice sales too. In addition, Amazon typically undercuts the market price for games in general. For the top selling games (like MK8), it will only undercut by a dollar or so. For other games (like Hyrule Warriors), it's $10+ off compared to say, Walmart.
So, even if you want to buy Wii U games at a discount, you can. YOu just need to watch for sales.
As for me, I am a happy Wii U owner. It's a great console not just due to Nintendo games, but it really gets you into the indie game scene. Sicne there aren't any 3rd party AAA titles, it's nice exploring the eShop and finding some hidden gems you might have otherwise overlooked.
