Wow, somebody actually posted a response :P That's the first time in 2 months, hehe.

@jlauro... that is only true of Europe weekly... In both American and Japan charts all software is tracked as long as it sells more than 100 copies in a week.

checking last week;
-In America the top 50 PSP titles sold 177k for the week if my math is correct... the software shows 246k
-In Japan all software is tracked too, but the PSP only has 25 titles that sold over 100 for the week, so the number is exact. (not all of those 25 are in the top 200 though)

To be added: top 10 selling titles in each genre. I am going by what the games are defined as on Vgchartz. Correct me if I have any mistakes/anything should be added. I am not combining sales for multiplats.

Spot on.  I know you were explaining why Rayman didn't sell well on 360 but is explains exactly why so many third party games have not sold well on Wii.  They port a game previously released on PS2, don't improve the graphics, add motion controls and expect the game to be a huge success.  If porting from an inferior system (in terms of graphical capability) didn't help Rayman sell on 360 which people regard as the king of software sales then why should such ported games sell on Wii?  If developers put more effort into their Wii games and built the game from scratch on Wii then they would see better success.  But of course they are too lazy and conwardly to do this.  Rather they take the easy option of making a port and then try to argue that only Nintendo games sell on Wii. 

Good point tuoyo, I've never thought of it like that.
