Europa Barbarorum is a modification of Rome: Total War based on the desire to provide RTW players with a more fun, challenging, realistic, and historically accurate game experience. Europa Barbarorum is a total conversion, though it covers roughly the same time period as the imperial campaign included with RTW. The modification affects all areas of RTW; all vanilla units have been removed, all new models and textures, a new economic system, new traits system, new scripts, and in general new gameplay. No area of RTW is left untouched.
It's huge super-modification, thats suprised me. Realy. I admire people who do this great job, because the basic Rome: Total War was fantastic game, but... in arcade style. That colorfull warriors, a-historic factions and places... But this people fix this! Now the RTW is one of the best simple strategy games ever. All historic factions, hundreds of units, realistic design is impresive. I think this version of the game should be basic version, but that's only my modest opinion. 9/10
