Coelocanth: I think it's still the vanilla version. I don't believe (from some of the posts by the GOG team on the boards here) that they plan to update it until the patch cycle for the game is mostly done with.
Yep. that would be a lot of superfluous work and not concurrent with GoG's usual MO (of course the good OLD games are already done with the patching once they come here).
So you get the vanilla version and the day one activation patch is included in that.
The first patch 1.1 you'll get as separate download file in your account (the game shelf) and the patch 1.2 is
here.
As of now it is neccessary to install the patches in order (accumulative), so even when you donlad now, you need to get both patches.
Probably this will also be true for the 1.3 patch, but we can't know that for sure now.
