This is by far my favorite strategy game.
For those of you who are new to Sins it will be a bit of a challenge figuring out how to play the game but trust me put the time in and it pays off. The difficulty of the game can be tweaked to suit anybody's needs, wether your'e looking for a quick 1 on 1 match against an easy opponent or an 8 player free for all against ruthless AI, or compete against real human beings online. Be warned though, matches can last for hours and hours, this can be a good or bad point depending on your play style. Visuals are great, so much satisfaction to be had in zooming all the way in on your massive fleets and watching them demolish your rivals empire in flurries of lasers, and explosions.
Long story short, if your'e into games like Total War, Glactic Civilizations, Supreme Commander then your'e definately going to want to pick this up. 40$ is a little steep though so look for it to go on sale, I was able to pick it up for 8$.
