I'm currently playing Shinobi and have made it to the last boss on 8B on Super difficulty with Joe Musashi. Given the time that I've put in so far, I'd have to say I've found this game generally easier than most of the reviews and commentary that I've read so don't let that scare anyone from playing, it's a limited but very fun action game. But, the last boss is notoriously hard and I hate having to replay 8B just to fight him again, so I made it through 8B this morning and have decided just to leave the PS2 on until I beat him. It's much easier to just try a few times and then repause if I have to quit, but be able to come back later right at him when I can. So, has anyone else left their PS2 for extended periods of time like this might take? Any problems experienced because of it?
