You know, this is the first NISA game that I will not be getting. Heck, I even got Generation of Chaos when I don't even have a PSP yet. The first Atelier Iris had great music, but the gameplaying experience playing was unfulfilling for me. I was not expecting the end of the game when I got there. I beat the last boss, but didn't realize it had been the last boss until a good five minutes into the ending. Then the game froze. It was surreal. I had a lot of fun leading up to that, but the ending just snuck up on me.
Then I started a new game in Disgaea, and remembered how much I loved that game. Now I'm 230 hours in, working to get some of the stuff I never got before (majins, recruits, ultimate weapons, liberating Priere and Marjoly, beating Baal, etc.). I figure I have another couple hundred hours or so of playtime before I really get a feeling of completeness, and can move on to Makai Kingdom while I eagerly wait for the US release of Disgaea 2.
