I wonder if my GTX460s are going to choke on this game; if it does, time for a new graphics card the end of next year.
The funny part is I still need a lot of practice with tactics on the first one.
Speaking of which let me ask a question: If the enemy engages me and I'm in defensive mode, only my direct line is doing any defending/attacking. The rest stand still. Is it better to engage the rest of the troops, or am I making a mistake to turning defend off in that instance?
That depends on your play style and the situation of the battle itself and your difficulty setting. Some people hold a reserve alwys ready to fill gaps and so forth and some people like to get all their troops involved at once. Lots of flanking and what not. The AI isn't all that smart(compared to a human). It can easily be bested with pretty much any tactic you choose unless you are severaly out numbered and have inferior troops.
