[Chronic Diarrhea]

Actually, one of the characters has aged since Tekken. Heihachi used to have black hair, and now he has white hair.

I doubt you would win all the time if you picked this game up. The ranking system makes it really easy at first, but as you move up several ranks, youhave to play more skilled opponents. The fighters for the most part stay the same, but their difficulty rises. In addition, you can still move up the difficulty yourself. So if you were playing on easy and had to face a 3rd Dan, it would be the same as playing it on medium and facing a 4th Kyu (lower rank) etc. I've only gotten Christie to a 1st Kyu so far, and it is already getting difficult against the 5th Dans.
