GOG has updated this classic to play on modern systems beautifully. I've played through the campaign twice and have played multiple one off games and I have only had a crash once and I'm honestly not sure what happened in that instance. It plays just like old Epic 40K (for better or worse) and is pretty true to the original rules. Its a fun game to run through and gives just that right flavor of classic tabletop wargame at 6mm scale.
