Mods for Barbarian Invasion?

[Olaf The Great]

Not really. It doesn't have the same features as EB. It is lacking the government system, the traits system, good skins and the map covers a smaller area. It is however a good historically accurate mod.
Invasio Barbarorum my review:
7/10 Gameplay
2/10 Skins
10/10 Historical Accuracy
8/10 New Buildings
4/10 Traits (same as RTW)
10/10 New Factions
68/100 or 68.33% or 6.83/10 Overall

I would not, however, suggest that you download the UI pack.

I have IB whats so bad about its skins, and there are extra traits,perhaps not the "stop in winter" thing, but still, and the Map covers exactly the same area.

And those are only a couple units, and even with those things, it doesn't deserve a 2/10,

I like both of the two Barbarorums.
