Frogboy: response re your query about how people win the game
In response to a flame, Brad said he wanted to know people's strategies for winning so in future he could program the AI to beat those strategies (and gave a good explanation IMHO of why they haven't spent huge amounts of work programming the AI yet).
So, amidst all the bug reports and complaints and requests for everything to be different, here's one noob's brief comment on what I've been doing so far. I'm playing at a very easy level and fast tech pace to get a feel for the game, and haven't played out to the end yet, so this is just a reaction to what the AI does in tactical combat.
What I've done so far is tech basic infrastructure, especally gold and research-related techs, then go for Leatherworking to improve my champions' armour, then go for archers and longbows, then go for heavy armour for my champions. I'm not sure I have useful comments about how I fight battles when I'm at an earlier stage because I lost about half of them when my troops were wimpy.
It seems to me that most of the monster groups I've fought can't cope with a line of blockers backed by archers. My latest army is three champions with Growth and Haste, with 3 longbowmen groups. The champs spend the first couple of rounds buffing the archers then protect them and attack when the AI gets closer. The archers do almost all the damage. I did similarly in an earlier (unfinished) game but with one champ, 2 archers, and some heavily-armoured troops. The AI does a little bit of concentrating on taking out one blocker but they don't seem to be quite smart enough at it; I've seen one monster switch from a heavily-damaged blocker to someone else. Maybe they also need to coordinate their approach better; if I hang back and wait for them, I get a couple attacking one blocker when several are further back and unable to help; when I attack them, everybody who can possibly target a single attacker goes for that one.
I don't think this is news to anyone, but I figured it was a good idea to give a try at the kind of feedback Brad was asking for. Maybe others with more experience can write similar but more insightful posts. I expect to have more of a challenge against an enemy faction at a higher difficulty level; the monsters don't have as many options as the enemy AI. I expect they'd have more ranged attacks, for example, and better use of spells. When I get that far maybe I'll post again.
