So I'm home from college for winter break and both my X360 and my GameCube are at school. The only console I have here is my barely-used PlayStation 2. And when I say barely used, I mean it - I've never actually finished a PS2 game before. I picked it up for bargain bin prices about a year ago as I figured it would be one of my last chances to buy one new, and seeing how it's the best selling game console of all time I figured I should probably have one. So for someone who is new to the console, what are some ESSENTIAL games to own? Preferably ones that aren't multi-console (though if it wasn't released on the GC I've probably never played it).
Also, here is what I own at the moment. What should I play first as I build up my collection?
