I bought World Championship 2010. So far its been pretty much the same as all the other ones, at least like 2007, which is the other one I have. Only real notable difference is that dueling is so slow. Whenever the opponent does something, it always makes you check the field. Thereby slowing the duel down. And I can't seem to find a way to turn it off either. I think I picked the wrong pack of boosters in the game too because my deck ain't looking so great at the moment.
