I'd reduce the bezels but I'd halt at a smaller size. I think the joycons are small enough as they are.
I played doom for the first time on Switch and I am sure as hell NOT going to get the sequel on that system with degraded visuals. Some of y'all on some next level fandom on this thread. Yes I would prefer to play some of these ports on Switch but in the end of the day you can play breath of the wild, Mario Kart 8, Diablo 3, etc on other systems.
Until switch gets more exclusives; Nintendo's other handhelds are still king.
Most of the games you are naming are ports. And yes, even Breath of the Wild is a port in my eyes.
"Better" is highly subjective. You don't even know how the new Smash Bros game will turn out. The same goes for Animal Crossing. What 2D Mario are you talking about? 3DS has many classics (Virtual Console), plus New Super 1+2 and Mario Maker. 3DS has Ocarina of Time, Majoras Mask and a Link Between Worlds plus the NDS Zeldas - I know a lot of people who prefer these to Breath of the Wild (I actually don't).
The 3DS has an abundance of new and original games. The library is better in quality and quantity IMO. Especially when it comes down to JRPG. Your statement regarding JRPGs is especially ridiculous. There are so many JRPGs on the (3)DS. The Switch will take years to even come close. Some old ass ports (Final Fantasy) and a downgraded version of Dragon Quest XI won't change that.
What if someone breaks into your house when you are not there?Yup. Only reason I still use my vita when I leave the house is because I'd rather it get stolen than my switch.
Gachas of all time? (Because MTX)
