But what about Disgaea 2? Your statement is supposed to be talking about the series as a whole. So here's the best I can figure for Disgaea 2 sales.
According to a statement from NIS they have sold 1.6m Disgaea titles total. Taking out all the sales we have from Disgaeas other than 1 and 2 that leaves us with 770,000. Taking out the Japanese sold for Disgaea 2 and if we're nice and give you 250k for Disgaea NA sales that leaves us with 370,000 to be split between Disgaea 2's NA release and Disgaea 1's Japan release. Once we're there we can either assume Disgaea 1 sold the same in Japan as Disgaea 2's 150,000 leaving Disgaea 2 with 220,000 NA sales but in my mind the more reasonable conclusion would be that the original Disgaea sold more in Japan and it only takes 200,000 sales of Disgaea 1 in Japan before Disgaea 2 is dipping below Disgaea 3's NA sales.
This was all done also assuming that the first two games sold absolutely nothing in EU, which may or may not be reasonable and not taking into account that NIS probably means shipped, but with a tiny game like Disgaea I doubt there are a ton of them sitting on store shelves.
