I have written a lot about the 3DS since I got one last year. The number of hours I spend playing it are starting to rival those of my home consoles. In other words, I can't seem to put the thing down.
The funniest thing about me own a 3DS is I don't use the 3D all the time. I do when I'm playing a game that supports it, but I'm sort of in love with the eshop. Here I can download all sort of older titles like Link's Awakening, Super Mario Bros, Earthworm Jim, etc. Games that don't use the 3D feature but are still amazing.
Of course since the release of Ocarina of Time 3D, I also love wondering about which Zelda title will get a 3D remake next. Last I heard, Nintendo said they want to bring a new Zelda game to the 3DS before revamping older ones. (I'm not going to complain about that) However, I would probably weep tears of joy if Majora's Mask 3D or Wind Waker 3D was announced.
So even though the 3DS had a slow start was it was released, I think it is going to a be huge force in the industry this year, and I'm ridiculously excited for its future.
