MTW2 isn't ending anytime soon. Hell, even the original MTW and STW are still played frequently.

And there's no reason whatsoever to make a Warhammer mod for STW. Older engine, and the setting is entirely different. The RTW engine and it's MTW2 successor seem custom tailored for a Warhammer TC - a little bit of working on the Europe map and you have a spot on representation of the Old World, and MTW2's Americas can easily be modified into Ulthuan and Naggaroth. We don't know how Empires will fare yet, so let's not make assumptions. Or else I might stitch a quilt out of your faces.

Gets cold up here.
