A bit hard to get into, but worth the effort.
Yes, Sins is a long game. In this A.D.D. world of gamers we seem to have today, it might not satisfy. It seems an RTS can last only 15 minutes max or people say it's boring. I say, go play tic-tac-toe if you want quick games. I long for more games where you can invest time into creation as it is far more fulfilling than playing ten quick matches. This is how most every RTS was in the beginning. The modern trend has moved away from this style. I say: "Bring it back!"
