Really I think the Neo is pretty good for beat em ups. That's mainly why I've had mine. Do wish they made more later in the systems life and less fighters though.
Edit: You know what there can't be many more than a dozen pure beat ups that are really great for the system. I was lumping together several genres in my head. In retrospect Capcom did a better job but the Neo still kicked the Genesis and Snes's butt. Either way I still wouldn't say its awful.
Kurtz, this is great. So glad to see you finally getting a title out on the Neo. It's seems like forever-and-a-half since you released the dev tools, and I've been waiting for something like this for a while. Looking great so far and I can't wait to see more.
