Different people have different tastes, its not only limited to one type. Many of those games may very well be better than the ones you mentioned (well blue dragon and lost odyssey are japanese though, so i'm not sure it qualifies on what the other poster was saying).
For example, im currently playing Disgeaa 4 and its an amazing game. Funny, well designed varied levels, cool characters, lots of customization. I find it alot better than Alan Wake, Too human, and Ryse. Its up to what you find more interesting, but to say one or the other doesnt have quality because you are not interested in it, is a gross overstatement. You may think that, but you can't force in on others, nor is it an absolute truth. Just for yourself.
Nippon ichi is well known for there wacky storylines and great characters! They are the masters of tactical rpg's disgaea being there flagship!
Highly underrated developer in the west.
