Ok. I razed Warwick, because I figured we could settle a much better city further south (where you're suggesting it now). The other city auto-razed.Note: I wouldn't raze any cities any more. We'll deal with the maintenance somehow.
I was also thinking that a Zulu mountain pass city would be great.
We could use border pops in the following current cities:
Ivory +3 tiles (not if we settle dyes)
Agra +8 (theater is 3t will do)
Lahore or Hyderabad +2 (need to whip theater on T+2)
Madurai +1 (need to whip theater by T+9 or so)
Birka +5 (needs a few artist turns at the end, after the current theater)
London +5 (needs theater on T+5, if we don't switch to Buddhism; otherwise also 10 artist turns and/or culture build at the end)
Hastings +1 (basically the same as London)
Coventry +1 (lots of culture building probably)
Some of those with only 1 tile are questionable, but I've had plenty of games where I come up just short at the end.
We also need two settlers for Agra-SW and NE England (4 and 5 tiles respectively). Mayeb these are not worth it, if we have enough in the hub.
