There needs to be an open-world zombie game that has both first person and third person. It should be a survival horror game except you can roam (walk/drive) around the whole city. Like airports, shopping malls, skyscrapers. It should pretty much be like GTA/Dead Space. What are your opinions?

How many times can I re-download items that I already bought from the PSN store. If i change my hard drive, can i go to my download list, and download them again or do I have to buy it again?

thanks

I am planning to upgrade my PS3 hardrive. It is currently a 40GB harddrive, i want to upgrade it to 500 GB. How do I do it it?

Will all my trophies get deleted? And how do I back up my files?

Thanks
