What do you believe are some of the flaws that all the games in the series pertain to? For me, it would be the lack of cohesion in the plot and how convoluted and all over the place it is. Also,( gameplay wise ) in games after KH2, the removal of equipment really bothered me due to the fact that I would have to probably grind to get my stats up and ( in the case of DDD and BBS ) abilities have to be unlocked in the most inconvenient way.
