Damn, its a pity I sold my Twin Snakes copy a couple of months ago, you could\'ve bought it off me.
Glad to hear you\'ve got a PS2 7 years late.
Quick tip, FF7 starts off crap, but stick with it, trust me on that one.
Add to your \'get\' list, Crash Bandicoot 3 Warped, best game of the series, also PS1 Spiderman if you can find it for cheap, its great fun. And if you like the Soul Calibur series, you might want to check out Soul Blade, worth it just for the intro sequence.
Oh, and yep, a PS1 Memory Card is needed for PS1 games. They\'re quite cheap now though, so no worries.
