I mean, dudes don't know how to make a bad game, and every game they do make is like fucking crack. And they are getting better and better- look at how amazing Persona 4 Golden and Shin Megami Tensei IV are!
They're consistent, and they make incredible games. They have a great portfolio of games, and they tackle themes games otherwise do not.
Also, they did make the greatest RPG ever, so there is that.
