i was searching for some info regarded PSN and XBL title's development time and team size.

Like i read that Everyday shooter was created by 1 person in few months.. Dead Nation was development in 2 years but i cant find how many people worked on it. 

so is there any site where i can find these type of information or any thread you know where such things were discussed.. I am talking about bit renowned titles, like pixeljunk, trine, Burn Zoombie Burn and other such titles. 

But any info in this regard will be appreciated

You can go to the main site of each developer and check. I know Joe Danger was made by a team of 4

thanks but usually they dont have such info. They focus only on the game features

70000 was the 'target' sales point for Burn Zombie Burn. No example of team size / time taken though. Estimates of downloadable games pins the costs on average around $500000 - $1m but for stuff like this it can really vary, from one guy making a game in his garage to something like Battlefield 1943.
