Yeah, so I just beat the alternate game in Kingdom Hearts: Chain of Memories. I had a total play time of just under 6 hours. I was level 37 when I beat it. Despite the fact that the second campaign (Reverse/Rebirth) is much shorter than the first, I found it more compelling. Also, since there was very little to do in terms of deck management (i.e., nothing), the game itself was more enjoyable. Overall, good fun.
