For real time stratagy players only.
The Good: First off the game has great visuals. It gives you the opportunity to make a large fleet of good looking space craft and duke it out with other empires. It has a great system of advancing by using a large tech tree. And each Empire has its own tech and ships that will seem like a different game each time.
The Bad: Each game(even small ones)will take a long time to finish. The audio, music, and voicework in my opinion sucks. At some points my ears started to hurt. The addictiveness of this game will cause a loss of sleep, eating, and possibly friends if you get to into it(which you will).
Overall Sins is a fun RTS game that will keep you hooked for a looooooong time.
