I think that mostly what I hate from modern gaming is the DRM, DLC, and other superfluous crap, although I do admit that I use my PS3 and Wii U to watch Netflix when I don't want to game. I also wish a few of my favorite developers of the past were more active.
On the other hand, I've gotten to play awesome games like Valkyria Chronicles and Ni no Kuni on my PS3. I've also enjoyed playing fighting games online.
