Turbo120

I'm thinking of getting a ps3 but I have some questions about the system and hope someone can answer them.

Q. How much memory do games like Final Fantasy 7 - Crash bandicoot and whatnot take up from the console's hard drive, I'm thinking of getting the 320gb system but I need to know what the average game file sizes are.

Q. What's the online gaming like, I Occasionally use xbox live which runs pretty smoothly with most games, I know online gaming is free with playstation but does it suffer from any major problems?

Q. This one may seem stupid...I know it has a built in blu-ray player but I don't bother with those, will the system run normal DVD's?
