There's really no excuse to not own the PS2. It's $100 for a new PS2 and it has some of the best third party support on the market. The first party support is pretty good too, considering Team ICO and Naughty Dog exist.
Considering I haven't actively played video games in years, I see no reason to buy one. While I'll admit that I do want to play Shadow of the Colossus, I find no reason to spend $100 on a system to play one game. Nothing from Naughty Dog catches my eye and I don't care for any of the newer JRPGs. I'm just not particularly impressed with the rest of the line-up. It's one thing playing games on a handheld. But it would take a pretty damn good game for me to want to sit down and play a console.
Spoiler alerts of course.
First of all, you make Squall out to be way more emo than he really is. I would hardly even consider him to be emo since he doesn't even outwardly show any emotion. He only really whines to himself. Heck, he doesn't even talk. Every other line he has in the game is "..." So what? He just likes to keep to himself. Anti-social =/= emo.
And even though both of them are jerks, Cloud also has a ridiculous ego on top of that. He's an arrogant know-it-all and he goes all raawrfgdfhsdfdfgjs at random moments for like no reason.
