I've played Star Sonata before, back when it was 100% free to play. Theres not many space themed games out there and this one is decent, the graphics are not very impressive but they are not bad either and the game it's self is good. A few years ago though, maybe 2 or 3 they changed it to a pay to play game where you can play for free up till around player level 20 then you have to pay a monthly fee. The games not that good, especialy when theres far better games out there with much better graphics and all that are free to play. A simular game that is free to play is Startport: Galactic Empires though it does lack some of the features that Star Sonata has like the AI system for ships. A better game would be a combination of the two that uses a cash shop for funding instead of a monthly fee.
