It seemed like it was pretty well along as far as mechanics and worlds go. One could only imagine how the game would have looked had they pursued the completion of the game. Why the hell would SOJ ask for SOA's approval for anything? After all, SOA did sortof drop the ball on the DC.
Anyways, SOR4: It's like Shinobi meets Final Fight - that combo system is awe-inspiring. This looks like it could have easily been the best beat 'em up, ever, period. The team attack is pretty cool, although looks a bit hard to actually do, but who knows.
The first person mode isn't as goofy as I expected it to be; it's like Doom using your fists. The game moves a lot faster than I expected in that mode. What I don't understand (and probably never will) when one can use which mode, or if it's selectable (like QIIIA).
Before I was just slightly irritated that it wasn't developed fully - now looking at it, I'm not sure why SOA canned it, seeing as how only a 10% completed game looks like it'd be more fun than Die Hard Arcade 2 or Zombie Revenge. So diehard fans got screwed twice - no SOR title for the Saturn or the DC.
Hopefully it does see the light of day, someday.
