Sorry I can't get the source right now but I read it was something like 10-20% more to port a game or if you doing them at the sametime like call of duty 4 then this won't be an issue.  I mean the most important parts such as the story and gameplay are usually the same but just gotta make sure they both run good.  You guys think developers will never figure out the PS3 and make excellent ports that we can enjoy and vise versa.

 I'm tellin you dude!!! Sony and Nintendo should join forces :P Let SONY keep making technology that no one understands yet, let Nintendo make crazy ass periferals and software! The world of videogames would be a great place :P Microsoft can stick to software and operating systems >_>;;;

Development time is spent on each version.  Spending less time on another version means more time on the 1st version and quicker game turn outs/more game turnouts.

It would work the same way as wound't you want the capcom games like dead risin or lost planet as well Bioshock the new naruto among others.  Where PS3 owners glad when they got oblivion?  Wheren't 360 fans glad when they got virtual fighter 5 etc.  I am only asking for 3rd party, by all means there should be come 1st or 2nd party that define the console.

Seconded.

 Edit: I should add to this.

 Multiplatform games tend to gravitate towards a lowest common denominator. Most time is spent on elements which apply to all platforms, while less time is spent customizing the experience to individual platforms. The end result usually means that the full potential of the game is never reached for any single platform.

 I guess I can agree somewhat with that, but then the third party games would be deemed shovelware :/ Theres just no way to compare to the quality of First or Second party titles :( Getting to work specifically on one system is a major advantage.

Wouldn't multi yield more games for gamers as a bigger pool can enjoy them?  Wouldn't it be nice to play uncharted on the 360 or bioshock on the PS3 etc.  Remember unreal 3 is coming out for the PS3 so hopefully the engine will now start to be on par if not better on it so we can see better multi games when using the unreal engine which is fairly popular this generation.

I apologize for my grammar and spelling as I am getting out of work but just wanted to reply quick to some of you who took the time to respond.

You know what, it would be even easier if consoles and games were cheaper, than we can all enjoy them even better, and enjoy their uniqueness on their corresponding consoles as well. (motion for Wii, online for 360, ...Cell for PS3, for example)

devs need to start making multiplat games with the PS3 and port them over to the 360. Would make quality 100% better for all ports.
