Bioshock is a bad example. The PS3 port sold 640k compared to 2.58m on the 360.

There is no data for how well ME2 will sell on the PS3, but I'm going to take a wild guess that it could be anywhere from 1/3 to 1/2 the sales of the 360 version. Quite possibly even less. Hardly "everyone."

Both of these cases aren't even comparisons though as both games had significant lead times on PC and Xbox platforms before the PS3 port.

Bioshock 2 sold roughly 1/2 on the PS3 what it did on the 360, which is probably a better indicator of how well a Halo game released at the same time would do on the PS3.

That's what I'm thinking.

FPS =/= JRPG

Halo and Final Fantasy XIII is a ridiculous comparison to make.

I wouldn't buy it

Why.

Dude, that's harsh. Maybe PS3 gamers just have different taste than 360 gamers. I play on both, but PS3 is my lead and I really don't like Halo. Most of the people I know who own PS3 don't like Halo and they don't even come on forums or anything. The two consoles have their different audiences, I'd be willing to bet that if God of War 3 came to the 360, it'd sell maybe 1.5 million in comparison to the PS3's 3.5 - 4 million.

Isn't it obvious? It is for the Xbox 360, which is his arch nemesis. I have no idea why though.

I think that if God of War 3 were released on Xbox 360 it would sell as well as Bayonetta, Devil May Cry 4, and/or Dante's Inferno did on Xbox 360. That's 66k, 1.25m, 55k respectively. And if Halo Reach were released on PS3 it would sell as well as Killzone 2, Resistance 1, and/or Resistance 2. That's 2.37m, 3.71, and/or 1.92 respectively. I'd leave COD out of it because it's a different sort of game. Sci-Fi shooters appeal to different types of people than COD style games.

So I think if God of War 3 were released on Xbox 360 it would average out to a total sales of 45.7k. Halo Reach on PS3 would average out to a total sales of 2.66m.

There are approximately 45.7k button masher fans on Xbox 360 that would buy God of War 3 and approximately 2.66m FPS fans on PS3 that would get Halo Reach. It's possible that these game's brand names could have an impact on their sales, but I think this is the bare minimum that they would sell. It's not about guess what ratio it would sell, it's about looking at what the genre sells on each respective platform.

Good point and good job with the research.

Ref MW2 sales difference. I think it would be about the same, though slightly more in 360's favour (i.e. EMEAA sales would be in higher on 360, whereas MW2 sales in EMEAA are higher on PS3).
