I'm wondering why games like Cod,POP,Assasin Creed and others sell millions in home consoles but then fail at portable.

 

Assasins Creed is portable exclusive to the DS. Although the VGChartz database mentions a game that has 0 hits. Man, surely the person who put the game in the database would've looked at it. No, I was the first

Some franchsies are just best on home consoles, I don't see why to single out the DS

I created it. And the DB for some reason doesn't register hits from the one who created the game, happens with all the games I add
