Ubisoft removed Tages and all DRM from Dawn of Discovery DVD version in a patch sometime last year. I believe it's still on the digital version (Steam, Impulse, GG) though.
So they removed Tages and went to the internet connection required with the DVD version or did they just remove Tages? My buddy put over 400 hours into that game and tells me to buy it all the time but I just can't bring myself to use Tages if I'm buying from STEAM or D2D or whatever. Game was on sale for 20 bucks including the expansion. Still not worth the hassle. There is no way to find a retail copy around here either. Maybe a handful ever shipped this way. Retail space for PC games around here is next to nothing. Best Buy and Future Shop are the only ones left with a shelf to speak of. Half of that shelf is WoW, Warcraft, and Diablo 2. =/
There was never a constant Internet connection required for Dawn of Discovery. It was released before the latest Ubisoft DRM used in games like Settlers 7.
In the very first patch for DoD they removed all DRM from the DVD version. From what info I can find in various google searches seems to indicate that the DRM still is on the digital versions (Steam, Impulse, etc.). The only DRM that was used in the first place was the 3 activation things (more activations can be gotten from Ubisoft).
So anyway, the DVD version with the patch has no DRM at all. Digital versions appear to still have the DRM.
This is similar to how Firaxis removed all DRM from Civilization 4 with the last patch they released.
Other games have done this as well so I do like the trend of removing DRM after initial release.
