1500 isn't as rare as you think. Robocop is a newer game, so more survived than you think. It's not like the EM and SS days,when ops would pitch games in the trash so other Ops couldn't buy them cheap. That's why 1500 run on something from the 70's and early 80's usually is much less than something in the late 80's and 90's. Those days, things would go to auction or be in warehouses with parts out of them, but still savable. it's an Ok game, but not as fun as most DE games from this era. POTO, TA, TM, and LA are much better games.
