I'm a die-hard fan of the CM series and expecting something similar, was initially dissapointed.
I'll have to say, now that I've learned the interface somewhat, It is a different and very intrigueing game. The simulation is more of a real time tactical game than turn based and I think that the pathfinding issues you speak about are determined by the skill ability of the individual(s) maneuvering and/or driving vehicles.
The strange paths they may inadvertently take (and especially at time you want them to stay in place!) in a way, simulates individual aggresiveness, how 'skittery' a unit is, and the fog of war. A little frustrating but realistic in that you feel you do NOT command automatons! (As your unit gains experience and skill, the frustration lowers somewhat - unless you loose em )
The cover may be abstract, but I don't think so, just that there isn't much in the way of 'ideal/perfect' cover. It is definitly LOS as I frequently find myself going to the unit level to see if recessed ground will give the proper cover/ concealment. I do miss the ability to enter buildings and levels but in reality, using buildings immediately sacrifices peripheral awareness and maneuvering
- Don't think that this is JUST a maneuver game though!!
