Well, if you wouldn't mind helping me out there too: I've just been skeptical from all the Steam reviews and such that claim the upgrade broke their game. Does the upgrade make the game any less mod-friendly than the 1.6 update that is already out for everyone? I would expect that the update itself, which is already available to all, would be the largest challenge for modders, not the DLC's additions, but I wanted to make sure before I purchase.
I know it's not the people's favorite update in general, so it might mostly be exaggeration and drama.
Also, would the use of something like the Anniversary Content Picker cause any problems with the STEP patches?
