I think wolf66 hit the nail on the head there. One thing I always loved about the CM series, and the WeGo system in particular, is that feeling of a chain of command, where troops are given their general orders and then left to the AI to adapt on-the-fly to unexpected situations. For me it just strikes the perfect balance between control and chaos and, realistic or not, it really 'feels' like you'd imagine commanding such a situation would.
That's the reason I stuck with CM in the first place, there's countless ww2 rts games, but only one WeGo one. And my opinion hasn't changed with the change of timeframe.
