I find fighting games, whether 2D or 3D, boring as watching a turd dry up. I like beat-em ups like Double Dragon and Streets of Rage, where there is a level to walk through, and enemies always coming at you. With fighting games, it seems like it's the exact same thing all the time. Different background to not interact with, different opponent, but always the same thing: fight for up to 3 rounds within a limited space, over and over again. At least for me beat'em ups have backgrounds you can intereact with and actually have you progressing through the levels.
