I also think that 2D gets neglected a lot of the time, as everyone is trying to do fancier 3D effects instead. Which is a shame as theres a lot of potential thats going untapped.
So to get a bit more interest in 2D games I've collected a little list of all the 2D-related journals on gamedev, and stuck them up in my journal header. *points* I only did a quick look around for journals to add (they're all ones I tend to read myself) so I've probably missed some. If you've got a journal related to 2d stuff then stick a reply here or send me a PM and I'll add you right away.
