Just saying since it would be an interesting way to not only test their skills but see if it could be done. Knowing the bunch here I'd say it wouldn't be too hard but it would take a while.
i could narrow down the genre selection by asking this: don't we already have enough mmo tactics games? (i still don't like the term mmorts as games labeled as such are rarely actual rts games)
It would be cool, but I don't believe the developers have the manpower, time or money to do this.
Meh... Look at the projects they've done over the years. They've got the talent and Time, I bet that if they went at it we'd have a great game in a few years
