JW: It's a little more focused on the single-player, it's not quite the same. I've worked on RTSs before, and while I've seen things done both ways I prefer the approach where you work on multiplayer first, because you're really establishing the core game mechanics. But here the core mechanics really come out of the single-player game. That said, what we've done along the way is to have co-operative enabled from the start. People play co-op all the time, and if there's something that doesn't work for co-operative play we fix it right away. For any mechanics that need balancing or tuning, we've tried to do that simultaneously. But we do focus on single-player more.
