We've only had our copy of eclipse for a short while, and since it's a big commitment to get a group to spend 4 or 5 hours together we've only managed 2 games so far. Roughly 10 hours for 100 bucks seems expensive, but what if you divide that across a group of 5 people? Then it's already down to 2$ per hour.
Every time the game comes to the table it looks like a better investment. All depends how you account for it, and how many plays you get out of it before you move on to the next new thing.
