Of this list ONE game is a 500K seller, although many of the US games, are Shovelware Ports of 360 titles, and certainly dont need to sell 500k to turn a profit.
I have highlighted in Blue games that VERY LIKELY have turned a profit at this point, and Red at ones who VERY LIKELY Havent.
Black ones are Multiplat ports, and we will never know what their PS3 Dev costs are, in relation to profits, and it doesnt matter, these games are designed to be sold on everything, not any one console.
If anyone disputes any coloring, Tell me, and ill update it, as this is quick and dirty
