I do agree to some point. But if we did that we also need to subtract all the sales for games that came with a controller or some other accessory
And why not? For example, people didn't buy "Wii Play" because of the game - they bought the WiiMote. They did buy Monster Hunter Tri though, and the Pro controller was just topping.
There are accessories bundled with games and games bundled with accesories, and it's not hard to distinguish the two.
I realize that - world ain't perfect. I'm not arguing againts a degree of exclusiveness, I argue againts making hardware inferior to the point that multiplats aren't even possible on it. How does that sound?Playable levels and characters are becoming more console specific as downloadable content for one console only, sometimes this is timed and lasts only a certain amout of time like Skyrim content being XBOX 360 exclusive for 30 days, other times its beacuse more money has been paid and they remain exclusives which is not so much anymore, but it does happen. Sometimes games are released for a single console and then become multiplatform after the exclusive period has ended. its not just hats and helmets.
What about 360 consoles sold with MW3 and Halo they would also count. PSP sold with copies of LBP, I can see the point you makebut it would be hard to do as you dont know if the console made the sale or the game sold the console, which should then count as a games sale.
I stick with my earlier argument re Nintendo games and multiplatform titles, I dont think anyone expects them to ever be fully multiplatform.
