These sins can quite readily be forgiven.
This game kicks ass. It's pretty much a combination of Homeworld 2 and any regular 4X space empire game. You could also see it as a space version of Supreme Commander, it's goddamn epic. Like, battles with fleets of over 200 ships.
Plus, there's absolutely no DRM, if you know what I mean.
While I describe it as Supreme Commander in Space, Sins has a much better UI. Supreme Commander wasn't all that great IMO because the pacing was slow as hell and you had to individually upgrade all the tiny little resource poiints which really got annoying. You also do a lot of teching in Sins but it's all very easy and intuitive, without feeling like a chore.
The only thing this game lacks is a singleplayer campaign with a storyline, but the open sandbox levels do an adequate job.
