I put 50 or so hours into Disgaea before putting it away and never touching it again. I like it, but it gets too grind heavy, and grind heavy ain't my thing.
I prefer srpgs where you can't go and grind multiple times in one map, and most of the fights are story based, making every fight seem crucial.
Suikoden Tactics is the highlight ps2 srpg for me, but if there was an rpg that has strategy elements and makes it tops, it's gotta be Dragon Quarter.
I just think I don't like N1 srpgs at all.
