I really don't get the "no more 3DS games, the Switch is out now!!" thing.
Like, it's just really weird to imagine "UGH, whaddaya mean Kirby's Adventure is on that stupid old thing. I have a SUPER Nintendo now!" or "Persona 4? More like Persona POOR. Get with the times Atlus, PS2 is old news." The idea that systems should just stop getting games the second their successor releases is so weird.
Did all the JRPG fans that had 3DSes for the likes of Bravely and Dragon Quest and SMT just throw them out when the Switch came out or something?
I know that, in my case, I never liked playing games on the 3DS to begin with. I've had one since launch, and owned numerous iterations of the system, and have poured hundreds upon hundreds of hours into playing games on the device. I've been introduced to series I've never played before. I've revisited catalogs I missed and relished in the opportunity to experience them. I've wondered how some franchises will ever recover when the dual-screen format is abandoned. There is no denying that the 3DS has delivered me good times and good feelings.
But I hate the 3DS as a machine, I have always hated it. I thought it was old, hideous technology the day it was released and that feeling has only worsened and deepened over time. To see a game I love like Luigi's Mansion reduced to that resolution and that control scheme is ruinous to me. There is no game I have ever played on the 3DS that I didn't wish I was playing on a better system. Every game I have ever played on the device is categorically worse of an experience, in my opinion, because it's a 3DS game instead of something else. I often wishes the 3DS had failed in the beginning when it looked like it might so Nintendo would have had to release a superior handheld that did the catalog justice. But Nintendo is good at sticking it out and turning things around.
A lot of people, I think especially fellow Nintendo fans, will say that it's all about the games and the hardware doesn't matter. I get that. But I don't really feel that way myself. I think a system itself should feel good to play, too. I don't think the 3DS ever felt good to play and all it's games suffered for it. I think the 3DS is a poor stage on which some great games were played. It's like fine dining on a paper plate.
I was ready to leave the 3DS behind in, like 2015. So every year I've had to continue using it has been undesirable to me. It's a system I don't really consider replaced by the Switch, and it's a system I would prefer to see succeeded with a similar form factor, but settling for another 3DS experience sucks the joy right out of me. I consider it a bad experience.
So a game coming out on the 3DS in 2018 is just a worse version of the feeling I've always had: I wish these games were anywhere but here. Or, at least, I will never stop wishing the 3DS had been something other than it was.
My personal and dramatic grievances with the hardware aside, I do think that the convenience and cost factor of juggling several systems at a time is discouraging to most players. I really want to play Demon's Souls, but it's locked away on the PS3, which means it might as well not exist for me. I don't have the money or the space to own a system for every older game I want to play. This is why backward's compatibility, or at least remasters, are so important to me. At least the 3DS got that part right.
I'm glad other people enjoy playing games on their 3DS. I just never did.
