- Races -
Elves are ALWAYS gay or queer-looking (I am looking at YOU, Warhammer Online! I played a Highelf Archmage)
Orcs are bloodcrazy beasts with axes.
Dwarfs drink beer and arer absolute experts in working in mines and processing metal.
Humans can't do shit against the other races but tend to have the biggest realm under their control.
Undead are made of pure EVIL ... with onions!
Dragons love gold ... and the meat of peasants. Nothing else
Wolves are evil as well, but damn weak. Never seen a real wolf, huh?
- Politics -
Kingdoms or Tyrannies are best. Democracy is for the weak!
War must have a epic reason. Not just fighting against another cult or realm because of diplomatic reasons or scarce ressources, but against an EVIL, DEMONIC cult or realm to save the world.
- Magic -
Elemental magic (fire, earth, water, air) are almost mandatory, if magic is implied.
Light magic is good, dark magic is evil
Fire magic does the most damage
- Others stuff -
Warrior, mage, rogue, archer, priest ... what else do you need?
Guns (except old one-shot pistols) are prohibited. Absolutely. Might and Magic VI with its Laser blasters doesn't count!
That are the most common ones I can think of.
