This will destroy your social life...
Graphic in disgaea is not for everyone, the style is 2d sprites with a 3d background.
Personally the graphic does not bother me at all, i actually find it very pleasing.
But if you are used to High Def Fps games, this might let you down, but if you want the true experience here, you have to look behind the graphic.
The main story takes about 20+ hours to complete, but the true challenge comes in the extra worlds and bosses.
With a level cap at lv 9999, it is a grinders dream!
By moving your characters on the map, unleashing combos and using clever tactics, reincarnate your character, level up your weapons, unlocking new monster types.
this will keep you busy for a long time.
It is a deep game, if you really want to find out why it is all it is hyped up to be, you will need to explore the netherworld throughout.
I highly recommend this dood.
