England.
But I've only played as England and Persia. Well, I've played as Arabia before, but that was with warlords and not BTS...
Who I will try out when I start playing video games again (I've made a commitment since August to not play video games until after Thanksgiving)
1. The Arabs again, its much better on BTS with the Unique power.
2. Germany, since you can have a huge empire and stuff.
3. America, since I'm American. Plus, theoretically, it should dominate. I'd like to see if it really will...
4. Rome. They were the largest empire in Europe, and I think they'd be pretty fun to play as.
5. Russia. They have soooo much land, and a Unique power that makes them almost impossible to invade. Whats not to love?
6. Spain. You would get to fight back the Arabs, and have a huge Empire in the Americas.
7. England again. The last time I played, I didn't win.
The first time I played with England, Germany dominated. I made several mistakes.
The second game, I had subjigation instead of commonwealth like I should have, and normal cities instead of colonies. As a result, my tech constantly went down till it was literally 0% per turn! And then my units went on strike! When the American Revolution happened, my British Muskateers were fighting American Riflemen! I should have just gave them independence, what was I thinking? Because America stupidly left one of there cities isolated, I capped it and that brought there war wariness up a lot so we made peace.
Later that game, Spain (who was dominating) declared war on the dutch. We (me and Spain) were about tied in points, but we were technoligcally backwards and they weren't. I had portugal and Inca as vassals, they had Mali. Spain had already capped France earlier. If they capped the netherlands, that would upset the balance of power to there favor. So I Declared war on Spain as a result of them attacking Amsterdam. I also got Germany on my side.
