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.
