The sales of most of the PS2 RPGs isn’t up to date, or lack US and PAL numbers.
One of the producers of Level 5 said in a Spanish magazine called Hobby Consolas that Rogue Galaxy had sold about 400,000 in Europe and America, which would put it at about 800,000 worldwide. Dark Cloud 1 & 2 are millions sellers, and there are probably a lot of games there which should be close to the 1m mark.
So your arguments are false, and then again, you should compare big-budget games with big-budget games, and not big-budget games with low-budget games which barely get any marketing (Disgaea,Air Tornelico).
