A good way to look at it .The better would be excluding the PS3 and 360 pack-ins and Wii Play and Wii Sports completely save the japan sales for Wii Sports .Nobody would be buying Wii Play if it wasnt for its bundled remote ,so in fact they are buying the remote and thats all .
Once we had this data cleared we should see the income created as its clear a 40 dollars game doesnt generate the same amount of benefit that a 65 or 69 dollar game .Especially when printing and launching both cost about the same ,the more expensive game has way bigger profit margin .And we should also look at first party sales in the average of the machine sales .Nintendo is following their path here and most of the software sold on the Wii is Nintendo themselves (Mario Galaxy,Mario Party ,Mario Strikers ,Metroid ,Wii Fit ,Zelda Twilight ,Link Crossbow training ,etc etc ).So if this is to be considered a gauge of what support the machine should get from everybody this has to be considered too .
