Any Nintendo non handheld console (unfortunately I have more good to say about the company than their consoles which is why I don't own any):
I like how they support co-op still.
I like how they seem to treat their employees (like taking a paycutt rather than laying people off).
As a company they seem to come off as a good guy.
xBox One:
I actually think Kinect seemed like a good idea, it is what sold me on buying a used xbox 360 honestly. Of course that is just for dance games but I think it could have potential if developers actually used it more.
It did have slightly better launch games. I think I could have found something I found moderately fun easier than on my PS4 while I was waiting for the games I want to come out (I tend to go more for third party stuff, Fallout is really what i bought next gen for).
The controller looks nice.
Microsoft is doing a lot better job of supporting and updating xbox. They're really making Sony look bad in this regard right now imho.
I could have carried over my witcher 2 save data to the witcher 3 game if I had an xbox one (hrmph).
The developer for State of Decay is sticking with MS (that's a good win for xbox imho).
Nintendo 3DS
I liked the idea of 3D (but I know I'm odd)
Pokemon, it is a game that is worth buying a Nintendo handheld if you can find a good deal. Glad I at least have a gameboy color to play the originals on
.
It does make it easier to carry around and be an actual handheld in that it is small (at least the original) and it closes (no open screen while in your pocket to scratch, oh, and it fits in your pocket)
Fire Emblem does make me a little jealous (least it looks really promising)
Nintendo 2DS
I honestly think it was a good idea to make a cheaper version without 3D for people who just want to buy something cheap for their kids (especially as 3d is not recommended anyways for young eyes)
Sony PSP (the only "Playstation" I haven't owned)
You can play Gran Turismo on it (*mutters at Sony whynotVita*)
I keep hearing about Crisis Core and I'd love to play that too.
Atari (Whichever one was around when I had my TI-99)
The games looked so much cooler!!!!! I was so jealous as a kid of anyone with an atari. I took my TI-99 for granted cause I did have fun with it but I always saw it as the compromised console for kids whose parents wouldn't get the Atari.
