For people looking for Ico and Shadow of the Colossus...
This --> http://www.amazon.com/ICO-Shadow-Colossus-Collection-Playstation-3/dp/B002I0J5FG/ref=sr_1_2?s=videogames&ie=UTF8&qid=1298439160&sr=1-2
For those too lazy or untrusting to click the link; both games are being re-released in one collection for PS3. For 38.99 USD on Amazon.com even, which is way cheaper than trying to track the originals down and buy them used.
I bought Shadow when it first came out, lucky for me! I'll never forget how it felt to face my first colossus.
I stumbled upon Ico at a Gamestop about a year ago and snatched it up right away. It freezes up and glitches out all the time. ;_; I'm too lazy to go check the disc, but I think it's a blue back. My PS2 is racist against those blues.
More on topic: I'm looking for Persona 2. Or I was. Until they released news that they were remaking it for the PSP. So now I just need to buy a PSP. I had a longer list of games, but I've managed to track down most of them by some weird luck. I actually found Persona 2 at a used game store but when they put it in a PSone to test it for me, it wouldn't run...
Trapt, Okage: Shadow King, Threads of Fate, Wild Arms 2, Chrono Cross, Legend of Dragoon, Shadow Hearts, Shadow of Destiny.. There's a couple off of the top of my head. I hunted for YEARS for some of them. But now they are on mah shelf! Some were given to me, some were dirt cheap, even at Gamestop. Some were expensive.. Urgh. Lookin' at you Shadow Hearts. Lookin' at you.
