One thing I am noticing is that the actual number of turns in starships is actually quite low, 20 is not a crazy number. Now a quick game per say isn't that bad...but I fear it actually breaks the economic model. The model assumes that you invest in your infrastructure to get a payoff later, just as Civ has always done. However, when you only have a less than 20 turn payoff....the payoff never really comes. Currently, I see no reason to invest in food for example. I use what food I have, but I would never waste metal in getting more...as by the time the new cities pay for the themselves I'm already at end game. I'm even starting to question if investing metal for more metal is really worth it except in the most extreme examples.
