yeah the ai could do with a little more improvement. Ships still get stuck a lot more than they should do (ie. not at all), and some more advanced commands like setting a path and guarding a ship would be nice. Although come to think of it this game may not be complex enough to warrant that.
Great game, but there's definitely a problem with cash flow. I'd travel 150,000ft but only earn maybe $10,000. This means I can't afford any of the 'higher-tier' stuff that i probably should do travelling that distance. Still lots of fun though.
