Can someone help explain the difference in Tiller games?

[Der Landser]

I wouldn't let the lack of 3D deter you from buying the SB titles that don't support 3D. The real genius in the SB series is in fidelity of the Orders of Battle, the scenarios and the game engine. For what this is worth, I play all of the SB titles in the 2D mode, mainly because that is the format I am accustomed to from playing board games and because it has a visually cleaner and uncluttered look about it. I find it difficult to quickly assimilate the tactical situation in the 3D mode because it is visually distracting.
