Quoted from SLAMT1LT:We sold hardly any Full Throttles so they're extremely rare but the theme killed it for collectors. Rare isn't always valuable.
Back when I was working for HP, I wouldn't have taken an Alien machine for free, knowing how many corners were cut and how cheaply it was put together. I am amazed all the games we sold are still working. Fair play.
Understandable, I started a game of Full Throttle at a show and bailed mid-way - thought it was awful
