For starters, design. This concept includes both amazing ergonomics (especially after the terrifying in 3ds - the previous Nintendo portable), and top-end appearance - the yellow color is just a cannon, much nicer than the dull black in my ps vita.
Next, I will note a bunch of games that they managed to release by the year 20. And if there were many good games on 3ds, nevertheless, the vast majority of them were, so to speak . specific. I don't like anime and similar style, while at 3ds percent of commercials 80 games, or even more, were "anime". Everyone is happy with the switch - and anime fans will find a mountain of great projects, and the rest will have something to play: both some relevant AAA projects (for example, Doom eternal) are coming out, and have already been released, and continue to be released, a lot of ports of the classics of 10-15 years: there are several parts of the assassins, the first two parts of the metro, skyrim, saints row, bayonet, civilization 6, alien isolution, the bioshock trilogy announced, the burnout remaster that came out a couple of years ago on ps4 and xone, the second part of xcom, and many other projects. In general, contrary to the stereotype about the lack of games on the switch, by the year 20 there were not just a lot of them, but a huge number. And that's not counting the great Ninka exclusives like Zelda, Mario Odyssey and Mario Kart, Splatoon, Animal Crossing, Luigis Mansion 3, etc.
To summarize, this is the first portable that gives you the opportunity to play full-fledged large AAA projects from older platforms anywhere, even though most of them are not the first freshness, they do not get worse from this.
