Nintendo's games aren't significantly better in quality on the whole than the games of numerous other companies that do more regular price drops, so I don't think that your analogy holds.
To OP, buy Switch games used.
It certainly holds for those of us who respect fun and game mechanics above all else. I still remember falling into The Last of Us hype as the 'game of the forever' only to actually play it and determine it was a slow boring game to actually play, then made a topic asking if it ever picks up and got berated because 'it's not meant to be FUN it's an EXPERIENCE'. The reality is, for those of us who grew up playing games in a skillful manner, we grew to appreciate games at their gameplay level first and foremost. This isn't just a Nintendo philosophy, but they are one of the only large publishers that focus on that as the priority.
The difference between myself and others though, I'm able to understand why others enjoy TLOU for what it is, and why it might be special to them, but the same people almost can never see why a game like Super Mario Odyssey is special. Hell, these sorts of people often go as far as to say Mario is always the same because all you do is save the princess, which totally ignores the entire ground up reworks the actual games themselves have been given for decades. This implies that for some reason they have chose games as their means to experience plot and value it more than anything else, a bit of a bizarre medium to choose for that, but hey.
I haven't played the new God of War yet because i'm absolutely unsure of what to expect, is it a fun game with a great atmosphere or will it be another slow walk boring game experience that i'm not particularly fond of? I've had to divorce myself from what many gamers now consider the most important thing, and look towards people who have like opinions more so then ever to determine if a game works for me. In that end, i'd rather pay 200 for a 3d Mario game than 10 dollars for Detroit, because I consider it entirely against my taste as a gamer. Since so many games have veered away from mechanics as the focus, it is becoming something I am willing to pay a premium for to continue having.
