Wow.. Now this should've been that article. It was well written, and he even said the exclusivity thing without making the article into a Sony fanboy's article. 

Nice find!

^ So you think that the PS3 version of Bioshock wouldn't have sold more copies had it released time and date as the 360 version?

That's my point.

Wrong.  Games sell most of their total sales in the first few months (if not days).  When they do a timed-exclusive release the hype wears off for the later release. (Mostly because internet asshole trash every game that normal people like and it's more costly to run too major marketing campaigns)

To sell more copies total they do a simoultaneous release.  (Unless there are significant barriers to development like figuring out how to make a game run on less ram and 96.3 processors.  That's not a knock at the PS3, it's just hard for most developers to develop for it... I own a PS3 and generally dislike the shitty manufacture of the 360.  In other words this gen has basically turned me off of traditional gaming.)

I know that this wasn't addressed to me but I want to answer it.  It's not about whether it sells more on PS3 or more on 360, it's about total sales.  It would have sold more on PS3, slightly less on 360, and more total... but that's what money hats are for.

Yeah exactly I didn't express myself clearly there. I was alluding to the point that you sell more collectively when you have a simultaneous release, when the marketing buzz is at it's peak.

Case in question; the PS3 Bioshock sales would have been significantly increased without compromising the 360 sales just because it's available at the same time.

While this is true sometimes there are exceptions to a rule that you (and sometimes I) assume. RE 4 on PS2 sold more than the Gamecube version despite being a late port. Enchanted Arms sold more on PS3 besides being a late port. UT3 on 360 is on its way to outselling the PS3 version.

There a few, but not many.

I alluded to exceptions, but focused on PS3 to 360. You're right.

Enchanted Arms sold more on PS3 because, at the time, there was nothing else to play.

RE4 sold more on PS2 because of the 100 million owners and because RE1-3 were on PS1. UT3 is selling more on 360 for similar reason plus 360 is better suited for FPS and online play (as far as fan opinion is concerned, not necessarily fact).

You're right...

At the time when EnArms came out for PS3 or 360, most people were still expecting the PS3 was going to be the JRPG console... like UT3 is more suited to 360... except that's turning out to be true.

Edit: For the record, 360 had 47 releases before Enchanted Arms. PS3 had 30 and not much after.

Just how exactly are these 'exceptions'? What you're proving is that sometimes a game can sell more on the platform with the latter release. 

These games on platforms with much larger install bases and target audiences still would have sold more had there been a simultaneous release with increased marketing.
