Actually, in games like chess, you have to plan and wait for the opponent a lot. And the wait can be excruciating.But even in chess there's many places I can go to play a 10 min a side game if I want, both online and off. Even professional chess games last for 3-4 hours max.
And that's my point. If a "simple" (but deep) game like chess can take hours, why should a more complicated game like Sins take less time?
In fact, it should take a lot longer, especially with two experienced players. Throw a few more players into the mix, and it should take days.
That nail-biting, can't lose because I've invested too much time, back and forth play I think *is* possible in Sins. And not possible in most other games.
In an one-hour RTS game, win or lose, big whoop... next! In a 6-hour "double tie-break" marathon, the stakes are a lot higher. Not exactly a gold medal, but still.
Once players get more Sins experience and a few more patches have addressed most issues, I think it'll really be good.
