Well the factions usually go or went like this: Khorne: Bonuses to Weapon Skill and Attack Rolls Slaneesh: Bonuses to Initative and Leadership Nurlge: Bonuses to Toughness, Wounds, or Armor Saves Tzeentch: Bonuses to BS ( for magic casting) and Armor Saves Now translate that into a video game. There's a pretty good chance the Khorne players will be OP over the other factions at first but hopefully they will balance these table top game attributes so that the 4 factions are on somewhat an equal footing.
Khorne: increased melee attacks, berserker's rage (as your HP are lower then X %, you earn some resistance on incoming damage, and an AP increase),every kill (i mean lasthit) give the restoration of X % of HP Nurgle:heightened HP regen and amount of HP, poisoned melee attacks, heartstopper aura (as some kind of "damage over time" spell) Tzeench: heightened armor penetration for ranged weapon, summoning the warp spawn, and some kinda of a powerful ability like possession for 60 sec and etc. Slaanesh: special class of weapon (all kinds of sonic weapon) , ability that damages you and give the AP bonus, increased vision range, different stimulators, poisons and etc..
As an ever-loving servant of Papa Nurgle, I say invoke the plague to heal your wounds and reduce ranged damage done to you, but slowing your movement speed. Good old classics up in here!
I really liked how the RPG Black Crusade covered character generation for chaos marines. You can't start out dedicated to a god, but your choices in skills as you level up show which one you prefer. There are negatives for choosing an opposing god after you have been dedicated to another. They don't seem to like it when you play with their ex.
For all the greatest daemon gods. If you are a great champion, finally receive the favor of the chaos god. Become an inmortal daemon prince of this god. Daemon prince Angron. Primarch of the world eaters
Actual fact, Angron destroyed his homeworld and after the battle was over he killed several of his own Chaos marines when they tried to contain him. Well they managed to do it in the end, after a couple of men died.
I think it would be ideal. I am a Word Bearer and thus its in my nature to honor chaos as a whole. However for the sake of gaming , i would be glad to see individual classes get access to certain gifts from the Gods , like spec trees. For example a melee fighter might choose Nurgle for a "tank" archetype , khorne for an all-out DD warrior or Slaanesh/Tzeentch for a more treacherous kind of gameplay , like an assassin. Likewise for a sorcerer , Tzeentch=pure damage , Slaanesh=buffs/debuffs Nurgle=DoT and maybe even healing.
Well he was killing his own men from the start when Emperor ported him on ship while he was fighting for his men. Angron never liked emperor for this.. and first thing Angron did to war hounds was killing them untill one managed to match him in combat...captain.
