@bed-head: You don't have to be good to play OCC, just extremely accurate and think twice or even three times before doing anything.
I still see not much point in playng the Greeks.
@Mark: Lets make a deal: If we lose on this one, we ought to play Byzantines OCC on archipelago AWE. Sure we will be able to make enough units to block all the coast and can win with 20K.
If the deal is acceptable, I'm in.
We cannot win with UN, 100K or Domination, so this leaves extremely unrealistic Space, barely doable Conquest and highly improbable 20K. Playing on 20K might be very risky because, as microbe noted, interrupting unit production might be too dangerous. Also, Republic might be out of the list of options simply just because we cannot trade for luxuries but hard to tell if we manage to build MoM somehow during the Golden Age. Getting this otherwise silly wonder might be our only chance to survive and build a reasonable size city.
The start apparently has to be rather good - food bonus and luxury, on the river obviously, not in the center of the map as well and some little breathing space.
