I played a demo of EU and it seemed incredibly dull, although that is just my opinion and to be fair I didn't play it for long. I really hope TW doesn't go down the EU road. While I want TW games to be more historically accurate and have more detailed management in general of factions, I think the reason the TW series is so popular is that it does offer so many interesting and unique factions and units. Although not to the extent of mods like EB though.
