I dont.I don't think you understand how game development works.
But several developers out there are willing to put in the extra effort to make a game for each platform independently. Other dont want to do this and make one copy then port it, which always ends up screwing someone over.
I dont understand how people can still complain about the ps3 game library. In the spring (i think) i saw an article comparing IGN's games scores for every platform. The ps3 had way more titles in the 8.5+ range than anything else. This year isnt much different really, with Uncharted, Ratchet and Clank, Infamous, Killzone, and Demon's Souls i dont see what is missing...ps 3 is a nice machine. for me it still has the same problem it had on release. not a good enough game library for many. BUT it has gotten better. Maybe by the end of 2010.
Im actually pretty happy with its library now I just want the mass amount of rpgs the ps 2 had. ps 3 has a few but its really weak in comparison to the xbox 360 or ps 2.
i go to where the games are that I want to play I dont care who makes it.
