On one hand, there is the novelty factor of its post modern premise, looping in the same time period and changing it's outcome over and over again. On the other, the game practically pioneered the idea of fedex quests, and is less about action and more about uncovering space opera subplots.
I remember dumping a lot of time into it back in the day, but remember not figuring out something basic about the ice level and giving up on it. That's on me though.
