Great little game. Actually not that little, as both campaigns will run several hours. Good replay value, as you can try different ships/upgrades in multiple campaigns.
Not sure why so many people are complaining about the island battles. Theyre really not that difficult... come to a complete stop asap to get range for your guns. I think theyre an interesting diversion.
And kudos for bucking the pay to play model and offering good game at a reasonable price.
