Now then I probably didnt give both games a fair go before so ill give you my rating of both just to put you straight.
Dark Cloud 2
Gameplay: 9.0
Graphics: 7.5
Overall: 8.5
KOH
Gameplay: 7.2
Garphics: 6.6
Overall: 7.9
Basically my reasoning behind all this is because I just didnt find KOH appealing at all when I played on it. I easily became bored and did not wish to play it anymore. Having played the previous Dark Cloud, DC2 had a lot to become if it was going to be good and I think it really did from beginning to end. The overall quality and finish on the game is why it is my favourite choice. But anyways the final descision is down to you these are just my opinions.
