There are two playable races: The Highmen and the Humans.
The Highmen are "good" humans, while the Humans are evil, following a dark lord...(read the story)
The Humans have a very very strong alley, the Undead,
while the Highmen have the Elves, Dwarves and the Haflings
as friends or allies. The Elves are strong, but they won't come forth and help the Highmen (read story). The Haflings are weak, only holding two cities.
Sinse the Humans have a stronger ally, the Highmen have more cities than the Humans.
The Highmen should watch out for attack from the orcs, and, eventally, from the Frostlings.
The Humans have the Dwarves as their closest enemy.
I would recomend the Highmen, but that's because I'm
more the "holy" type of player (my favorite race is the Elves)
