Legend or Mythology?

I really like this games sort of Viking theme, so I was wondering weather it should either stay more true to the Historic Vikings/Germanic/European Tribes, or also incorporate their Mythology such as Thor, Magic, etc.

Also: The Romans were in the same time period, so we could also have some Roman stuff, if people wouldn't mind. From the view point of some of the Germanic tribes, for example the Gallic tribes, the Romans were the bad guys. Maybe there could be enemy AI Romans :)

Historic:

• Get rid of the goblins.
• Get rid of Skins that don't match.
• Add goats, wolves, and maybe boers.
• Add spear
• Add forests.
• Make teams feel more like tribes.
• European terrain instead of deserts. (Grass, dirt, snow.)
• Wooden structures, and maybe some Roman forts.

Myth:

• Add mythical Animals, and keep the ones we already have.
• Add Magic.
• Keep the Middle eastern desert/structures.
• Keep non themed skins

What do you guys think?
