I think so, yes. There's still good games on the platforms which don't use the wi-fi, so there's still a lot of fun to be had there. I mean, the Gamecube only had internet for one or two games, and only if you bought an addon, but it was still great.
Yes, I use it to play single player games, and games which support local multiplayer with a link cable like the Gameboy Advance which requires a cable to play local games with friends.
I mean... probably? Most of the games I play are singleplayer, but it really would immensely stupid to not support wi-fi on devices released in the modern era.
Yes! I don't play many games online from Nintendo, I mostly always get consoles from Nintendo to be able to play with friends and family in the same room and this company does a great job in making games of that style. It's the only company that still seems interested in split-screen multiplayer, because it seems that it's disappearing. So, it doesn't matter that much to me if it has online play or not because I prefer local multiplayer.
Most definitely, because nintendo would have included some kind of linkcable way to play pokemon anyways. When it comes to pokemon, it's all about that competitive play.
No, I would not have gotten the 3DS if it didn't have WiFi. An important aspect of having those consoles and devices is to play with other people, usually that requires internet.
LOL... It would have sucked a lot without WiFi, so unless they sold it at a super cheap price, I don't think a lot of people have been interested in buying it... I mean, it's 2014. How can it not have WiFi in this day and age?
