Prince of Eckmühl
This may sound odd coming from me, being so closely associated with ACW games that employ sprites, but, for most purposes, I'd just as soon have a 2D map and symbols.
Sprite and/or 3D art is expensive and drives the cost of developing a game WAY up, so much so, that it's hard to justify the largely unrecoverable expense that a developer incurs when it builds what our readers refer to as a "wargame."
I'd also note that there's something of a myth out there, and it goes something like, "wow, if the developers would just do this in 3D, it'd be a hit!" In the overwhelming majority of cases, I simply don't believe that's true of this little niche of the gaming world that we inhabit.
As always, I'm not celebrating the above realities. It's just the practical side of me, the pragmatist.
