I got Disgaea Portable recently from Play Asia (it took the longest of any order to arrive -- nearly one month after it shipped). I never got around to playing Disgaea for the PS2, but I did play La Pucelle, so I am more or less familiar with the game world and some of the mechanics. I'm totally addicted so far. Since I haven't played the PS2 version, it's hard for me to say how the PSP version compares, but I think it's pretty much a perfect port. Load times are very minimal and the graphics look great. The character development and item upgrading system is very deep, and the random dungeons in the item world make it possible to play this just about forever. I haven't entirely figured out the "geo panel" system (not sure if they called it that in the English version). So far, I prefer the way it was done in La Pucelle, and I also like La Pucelle's idea of "converting" enemies on the battlefield better than the system in Disgaea (so far) but those are minor quibbles.
I wish the PSP had more games like this. I mean, most of the RPGs on the PSP are ports anyway -- why couldn't they pick games that are actually good to port? Of course, with Final Fantasy Tactics coming, I guess maybe they have gotten the message. Unfortunately, this game is not import-friendly at all, so unless you can read Japanese you're probably better skipping this. I don't know if a US release is coming or not. We can only hope.
