The Culture Minster has performed some analysis based on the archives of our great nation. Minister MOTH feels that there is no immediate need to investigate either Akkad or Tenochtitlan. Minister MOTH does wish to recommend that we rush build a Colosseum in Epolenep as soon as we can (turn 1) as this should give the edge in culture back to Epolenep.
I would also like to point out that in
this policy poll the people voted for a 'moderate' level for fighting culture wars. Specifically, the use of 'investigate city' was not selected. This would mean that any such use would need to override the policy by attaining 55% of the vote with a 13 person quorum.
Research and Analysis:
There are 2 primary cities in question:
1. Akkad - This city just (8 turns ago) passed Epo in total culture. It has not yet reached 1000 culture. Within 6 turns Epo will pass 1000 culture. By watching when Akkad's border expands (out to see) we can guage how much of a lead Akkad now has. What does Akkad have? My guess is an Ancient Library - 6, Catherdral - 3, University - 4, Colosseum - 2 = 15 cpt. I'm guessing there is no temple based on old saves (90 BC (t123) - no culture; 110 (t133) AD 10-99 culture; 460 (t-161) AD 100+ culture) - this was 3 cpt to expand to 100 culture in this time period - thus a Library.
In any case, there is only one short-term peaceful solution: Rush a colosseum as soon as possible. On turn 1 this will cost 444G and will boost culture per turn to 16. This will start gaining back the deficit. I don't think an 'investigate city' is worthwhile as it couldn't tell us much.
2. Tenochtitlan - This city was estimated to have over 3000 Culture. I would estimate as much as 33 cpt - Palace 2, Temple 4, Library 6, Cathedreal 3, University 4, Colosseum 2, Oracle 12, Sun Tzu's 2. We are on turn 249 so there are 301 turns to go. Intentionally overestimating and given eventual doubles for 11 more cpt + 2 for Research Lab this is 46 cpt. 301 * 46 = 13846 + 3000 they have now = 17000 at game end. This city will not win 20K unless they manage to build more great wonders. I do not see a need to investigate this city unless it crosses the 10000 culture point much earlier that expected (before turn 350).
