Given the number of games covering the allied operations, I am supprised the limited nature of Cross of Iron.
Considering the massive nature of the eastern conflict I would look forward to the series being extended in that direction, possibly with a more in depth coverage of the initial blitzkeig for instance.
It's worth playing the Der Ost Front mod for Close Combat 3. Wider range of units and upgrade paths, larger campaign as well with more maps.
