Hmm, going by it's general reputation on miniatures forums I'd say you might get $10 out of it from someone looking for a copy for nostalgia reasons. If you find someone, and they want two copies let me know :D
We played it a lot back in the 80's but game design has moved on, I doubt many people still play it.
Cool. Thank you.
Did you play both Challenger II & Challenger 2000?
