In the game as it is, the tactics are trivial, and from multiplayer reports the system is poor for player vs. player too - because it just isn't well thought out. For example, whomever attacks first has a big edge; there are a bunch of hokey exploits which I suppose could be called tactics, but which certainly give an edge to gimmicks. (e.g. attack with horses and retreat to where the other side can't get you.) You simply lack the tools - like opportunity fire - that are essential to making an I go - you go system have game depth. I don't just find this system poor with the current AI; I think it's just plain bad design. Switching to sometime on a tactical map (where "stacks" can duke it out) would really interest me, by contrast, and I think that it could be done well. The violence done to the game on the large scale just doesn't match the return from the new battle model, at least for me.
