Cool, I have some great tips:
1. On your first try, do not play ironman, in fact I recommend against playing ironman altogether because shit ain't fun.
2. Do not enable permanent destruction of city, it can lead to your endgame being fucking barren.
3. Economy, depend on you, difficulty always set hardest.
4. Your Bros, now at the beginning, focus on getting on the most "normalfag" background (farmer, fisherman, brawler) and avoid the cripple and beggar, in fact, savescum it, buy one and if you see he's shit, reload.
5. For strong melee stat character, give him an axe handed axe and double grip it until he's good enough and you have gold to buy a 2nd handed sword. Ignore shield, yes, double grip fucking rocks. And sell the early 2nd handed axe, it sucks.
6. For ranged character, ONLY equip bow to character with good ranged state (above 50 to 70), otherwise, give everyone a crossbow.
7. Orc party can be farmed for money early on, because their weapons sell and the Orc young and berserkers have next to no armor.
8. Armor should be farmed, not buy, use dagger puncture on bandit/raider and undead heroes to damage them directly and big chance they will drop the armor (remember, armor/weapon have a bigger chance to drop the LESSER damaged they are).
That's some just tips, this is a very difficult game. You should give Steam guides a look out, especially the beginner and perk guides.
