The only way to disincentive remasters or ports is through backwards compatibility so it's in your best hope for console manufacturers to retain backwards compatibility for the next generation ... 

Oh it will! First off despite what some people in this thread say... A huge part of gamers want ports, they want remasters and remakes of older games and perhaps the most important part. The cost of developing games that's up to people ludicrus standards are massive. Ports and remakes of existing games gives them an extra 'easy' cash and that is hard to see past from a corporate perspective. Especially since the uprising of micro transactions. This is the reality going forward if we want to have single player games, I'm sure of it.

Also, why are people so upset about it? Ports and remakes makes the Q1-Q2 schedule look a lot more attractive than it would without ports. A remaster / Port is a lot faster to produce than a brand new game. You cant replace a port with a new game in every single instance. 

As Machina and Mbolibombo have pointed out, this is the trend for the generation. PS4 and Xbox One's first two or three years have been marked by ports, remasters and cross-generation titles. Hell, look at the HD remasters and remakes that have launched in the last few months or which are still being confirmed for those platforms: it's a feature of the generation. It's a reflection of increasing costs, increasing risks, shrinking profit margins and customer demand.

Personally Switch, for me, strikes the right balance. There's so much content coming on every platform these days that's there's bound to be a mix of major titles, ports, indies, middle-tier, remasters and remakes. The market is so big that it's simply not possible to keep up with every major or quality release across every platform - 20 years ago that wasn't a problem. Case in point, I owned an Xbox One and Xbox 360, but being a multi-format gamer, I never got round to playing the Dark Souls series. Between multiple formats, other hobbies and my personal/professional life, there's only so much time and money most people can commit to gaming. Switch, with its portability and versatility, is a good antidote for that.

Switch has a mixture of new titles (Kirby, Mario Tennis, Yoshi, Fire Emblem, Octopath Traveller, No More Heroes 3, Lost Sphear), titles that are new to me (Dark Souls, Dragon Quest Builders, Ys VIII) and titles I don't mind replaying (Hyrule Warriors, Bayonetta 2) to keep me satisfied.  That doesn't include indies and doesn't include titles yet to be announced for the year, obviously. You might have played these ports or remasters before - but that doesn't mean everyone has. They just have to be new to enough people to be worth playing. That's why GTA V and Minecraft are still selling on every platform under the sun. That's why Rocket League is going from strength to strength. It's why Mario Kart 8 DX has shifted 5 million copies and counting.

EDIT: Finally, I want to address your baseless 'shovelware' claim. Switch had a higher Metacritic average across all titles last year than PS4 - it had the highest number of 75% plus exclusive titles after PS4 and PC and the highest number of 'great' titles across every platform last year (90% plus). The average Metascore of Switch releases in 2017 was higher than that of (from lowest to highest Metascore) Vita, PS4, and 3DS, equal to Xbox One (which had fewer good or great exclusives) and only lower than PC (highest Metascore of the year). Not the perfect metric by any means, but one that, as far as an objective measure of quality for 2017 releases goes, is about the best thing we have. Consider that Switch had been on the market for 9 months when that happened, and in terms of the number of quality releases and the overall quality of its library, it's holding its own against systems in the prime of their lives and against PC, which has a vast quantity of software, and I think, if we are going to attempt to be somewhat objective about it, Switch's critical and commercial performance in 2017 flatly contradicts your claims. 

Nintendo isn't making up for anything. They are porting wii u titles to a bigger audience. And ports don't come from 1st party alone on all those systems.

Ports of last generation titles aren't a bad thing to close the gaps left by the lack of "new" games.

The early days of PS4 were full of this kind of behavior from both Sony and 3rd parties. Grand Theft Auto 5, TLoU Remastered and the Uncharted Collection are all among the PS4's best selling titles, and 2017 saw the Crash Bandicoot Trilogy and Skyirm both sell like crazy.

People want these games, and they're quick and easy for developers to make. And on top of all that, it's not like many people got to play them on Wii U

As long as Nintendo keep pushing out brand new games to go alongside the remasters and ports, then there's no real problem to be seen and presenting it as a problem is silly.

It's not even been a year yet for Switch.

Curl, no one made you buy the Switch. Especially at launch.

As for the ports, people are buying them if they werent companies wouldnt keep making them. The people who are actually bothered by this are in the minority.

Neither you nor I get to decide what types of videogames someone else likes or dislikes.  If they only want to play point and click adventure games or puzzle games or even games about cats, they have every right to do that.

Personally, though I do want to play Zelda, I have little interest in the rest and still I have plenty of games to choose from.

Because the games aren't ready to be announced / released yet. I'd rather have a finished product over a rushed game. 

Obviously I wanted a "big" game in the first half of the year (something like Fire Emblem), but there's still plenty for me out there. 

The new narrative has arrived. Shovelware! Didn't take too long.
