My only concern is that the AI won't be difficult enough for the final product. It's weird how NES games are still hard as hell, but most newer games can be easily beaten. If the online mode is successful, then obviously there will be a lot of challenges against other gamers. I'm wrecking every character right now on this demo, so I can't even imagine what I could do with someone like Fedor. Overeem vs. Overeem on Legend is still my favorite match up though. 8-15 second fights are pretty wild. Still looking for 5 round wars though, and I can't get that on the demo.
