EA uses a model more multi-platform developers should adopt. They develop on the PS3 first and then port to the 360. The reason being that the PS3 is more difficult to develop for. This doesn't make the PS3 worse, or better for that matter. It's just the fact that Sony's a hardware company and Microsoft is a software company by nature. By using this model all the versions of Dead Space came out identical. This is a shining example of how creating a cross-platform game is done. I chose to get it for the PS3 because I liked the look of the PS3's (initially free) downloadable armor better than the Xbox. I ended up sticking with the Scorpion (pre-order) rig instead though.
This post seems out of date. With time comes familiarity. With time comes better development tools. And with both of these comes better looking games for the PS3.
Those developers that develop games on the PS3 first and then port to the 360 do this not because the PS3 is "more difficult to develop for." But because the hardware requires more specialized programing to be put in place ahead of time as opposed to leaving it out -- which is what happens if a game is developed for the 360 first. Doing this is a positive for both platform since most of the code is reusable on the 360. Developing on the 360 first leaves out too much of the critical Cell/SPU code required for optimum performance.
IMO, Dead Space on the PS3 looks a bit better than the 360 version. How so? Deeper and richer colors. Don't believe me? Check out the numerous comparison videos on the web. Google it.
The PS3 has come a long way!
I remember back in the 80s when American car manufacturers were criticizing that Japanese cars were "too complex" and "too difficult to work on." Etc, etc...
I've heard that color thing with some other games too. I'm curious what the technical reason is for it. I mean I know the hardware's got more under the hood, but seems strange that translates to color (IF of course you remember to set it correctly in the system settings!)
I still don't own this game though (or a lot of others) because I can't decide which of the current gen systems to standardize on! This summer I was going to do PS3, but then Microsoft fixed the noise problem more or less, and Sony removed backwards compatibility, so...
