Two DLC packs announced for Disgaea 4 in Japan

@HardBoiled2009

Imagine FF Tactics style gameplay (combat wise). Then add in the ability to power up ALL items (even potions and chewing gum!!) by going "into" the item and beating random boards.

Add in a little flavor text on every single item (my favorite flavor text was on the sword called the "Bezerker"... the flavor text was "My love for you is like a truck". A Clerks reference in a JRPG? MADDNESS!

So many things to do in that game, its often hard for newcomers to wrap their brain around it in less than 100 hours. You can also steal a pirate ship from INSIDE AN ITEM and use that to pirate the item dwellers and steal more treasure.

...or you can play the regular campaign. LOL

In order of awesomeness: Disgaea 1, 3, then 2 (IMO). Rent or pick up Disgaea 1 and you'll know what this series is all about.

Also, just adding to that list.

Disgaea 3:
You can also delve straight into your own characters bodies through the help of a Prinny with an Afro, in which all the enemies are based on that characters levels, and you even have chances to fight copies of said character (which opens up the chance to duplicate items legitimately, stats and all).
And, adding to the Item World Pirates of early games, you fight them, you beat them, and then you steal their ship! This lets you raid the items Item World for booty and pillage some rare-type NPC inhabitants. That is called Reverse Pirating.

And of course, you have the Prinnies.

Explosive when even tossed about slightly, and have a penchant to punctuate their sentences with "Dood!". It may sound like they are annoying, but they are pretty much the mascot for the series, enough so they have two spin-offs which are actually pretty decent.
