International Battle, me vs computer, hard difficulty, large unit scale. v1.5 modded (mods included)
This battle started out as a test of my new personal mod. The mod makes it so that every faction can train almost every unit its neighbors can train.
The three factions in this battle were Carthage (me), Numidia, and Spain, in a free-for-all. I did not originally intend to play the entire battle through--just enough so that I could examine the units to make sure there were no bugs in them. So in the beginning there is a really long deployment time (it ends around 170000) in which I don't seem to be doing anything.
Then I decided to just play the battle anyway. I had no real strategy in mind, and decided to just wing it. The result was the one of the most unusual games I've ever played.
