I agree with hotrod- this will probably play like a slightly underpowered Deity in many respects, if past maps are anything to go by, and I fear what cracker will do when we finally have a Deity game.
This month we have industrious workers!

The Ottomans are a great deal of fun, and I

Sipahi (see Hot3 for details.) At Emperor, I think I actually prefer the UU later, as I might be caught up in tech enough to use it effectively.

Persia is a strong civ, but sometimes I don't get a chance to use Immortals in time for them to be useful for anything but triggering a GA.
I won't say what I will do with the map itself yet as far as initial exploration on turn 1, as the old trick of right clicking on tiles to get a better idea of what they cover may change my decisions. The extra warrior (if that is what the third unit is) will look for any nearby high-food spots for a settler pump, as I suspect the previous posters may be right about the lack of bonus hidden food. If I find it nearby, I'll get a settler there fast, if not, I'll use the extra shields not spent on producing the warrior to finish my granary quickly.
Just a note to those not used to Emperor level: use lux tax judiciously early on. In the early turns, unless barbarians are seen immediately, it's better to uncover tiles with your warriors before you build your MP unit. (Entertainers early on are also a generally bad idea unless you are in a desperate situation or are the extra gpt it would take from an important tech deal.) Don't sabotage your economy once you get it going, but early on micromanaging the sliders can yield large benefits.
