I've got some good memories of Time Warp in my youth as well. Only played the BF type and it was a favorite. From the pics the BG does look good, if it was close by I would be very tempted, a year ago $1500 would have been
snapped up, I agree it's close to top dollar in today's market, but if the pics are accurate on condition then I reckon $1500 is ok for a tidy example of this game.

Cheers
