You are clearly not hereto have a discussion, and don't seem to be capable of having one due to your mental deficiencies.
To attempt to try and communicate with you a last time, which I really shouldn't given how you just crashed the quality of the conversation down to a 2nd grade level with your "mature" post above as quoted, if you had actually read anything that was written you would know that I'm comparing classic/nostalgia Nintendo game sales on one system to other Nintendo systems in the past (which include the minis btw though you have to gauge those differently since the games are build in), of course this may seem obvious now, but it's clear you never picked up on that, because you were looking to be confrontational instead of rational.
Currently, on the Switch older Nintendo titles aren't selling as much as they were before, and given many games aren't even on the Switch that were on some of the other systems, this should also be rather obvious but apparently it's not. It also helps Nintendo is transparent about sales.
Compared to Wii, DS(all models), 3DS(all models), The switch(all models) has had less attention and sales of older Nintendo titles for various reasons (except for the Wii U), of course this could change in the future but as of right now the pull and money for the older titles isn't matching previous systems, and I'm sure the minis didn't help with that either considering how successful those were.
So the question is why? Because the die hard fans are shrinking and the new gamers young or old to the Switch and the eco system are not making up for the shrink in nostalgia die hard, opting to instead buy more original/newer Switch titles than old classic Nintendo games. This doesn't mean Nintendo is in "danger" as clearly new Switch games are making vastly more money than old retro games (duh), however it does mean that if they want to still rake in as much dough as they have in the past they will have to balance their prices with to increase volume. You are already seeing Nintendo starting to change their strategy for older game prices and marketing, limitedly, due to this that they hadn't done before. There's nothing controversial here at all.
Rather simple really.
