I played the coin-op version of this game when it came out right after Star Trek II was released. I could have spent an infinite amount of quarters on this game if I had the money. Years later, I saw a sit down version of the game, however, it was unplugged and the restaurant owner said it was broken. Later, I got an Intellivision for playing games at home. And when this game was ported over to home systems, EVERY OTHER CONSOLE except Intellivision had a version. I was crestfallen. I hope GOG would please preserve this game, I would buy it in a heartbeat. I have missed the opportunity to play it foor more than twenty years. Please restore it since Sega will not release it on any of their collections.
