Crisis Core and FFVII

I recently bought Crisis Core for the PSP. It's pretty good, but the combat system gets kinda bland after a while. Of course, no one would ever buy this game for the gameplay, because the story is incredible. Unfortunately, I've never played FFVII, so I'm probably not getting a lot of the stuff that eludes to the original. However, I decided that I needed to play the original so I could experience the story in its entirety. So I went on Ebay! And saw the going price... I got a relatively good deal of $50 for a used Greatest Hits version. $50! For a used game! But now I'm waiting for it to come so I can pop it in my PS3 and see if I wasted my money. I also watched a movie called Midnight Run. It's from '88 and I reccomend renting it, as it is quite funny. In fact, it's the only movie I've seen that really succesfuly pulls off the action/comedy genre. It's funny, but not in an Anchorman kind of way. Plus it's got some actors who you may have heard of like Robert DeNiro and Charles Grodin. So ya.
