I actually bought a PS1 about a year ago, along with about 10 games. After six months, I sold the thing for about half what I got for it. What's the big deal about the Twisted Metal series? Seemed like whenever I careened into a wall, I wound up floating in wall-limbo, unable to move. The only games I miss from my PS collection are Darkstalkers and my personal favorite Capcom franchise, One Piece Mansion.
Being able to play One Piece Mansion on the go DOES sound cool, though. I'm not sure if it's 180 bucks worth of cool, but still!
