You never need to build the colosseum so I don't understand your point. And you talk about saving a tiny number of coins by not buying units in barracks and then say you would delete housing?
I already posted my analysis for 2 GBs. Why don't you actually show me your analysis that makes you think Im wrong?
Okay I am going to try to give you the best answer I can to both of your response in one response, someone can check my math as I did a fast calculation.
Yes delete the houses as I generate coins through other buildings that were laid down when I opened up the space, such as Tribal squares which gives coins and goods along with population.
Your arguments is that a level 15 Haigia gives more forge points than SOK's in the same space, so here goes. The Hagia space is 7x6 (42 squares). The SOK's is 2x2 which means ideally I can put 10 SOK;s in the same amount of space, plus get coins from each of the SOK's, which is more than I would get from Houses.
Now laying down the Traz means I don't need to build all the barracks and I can choose what I need to have, plus I get more happiness than the Hagia. So has a fighter for GE and GVG purposes if I didn't have the Traz would mean that I would need at minimum 4 barracks. Which comes out needing (LMA numbers) 3124 in population. That is between 15 and 16 houses that is needed for population. So the 15 to 16 houses I don't need I can have the 10 SOK's.
Now for the 6185 forge points you spent leveling the Hagia I could spend on the either the Traz or CDM which would give me for the Traz a Level 12 getting 11 units a day with enough happiness to make the world a better place. Or a Level 13 CDM that would provide 33% attack boost and give 8 Forge points a day.
So by choosing the Traz over the Hagia I am producing twice the amount of forge points, saved on population needs, increased my coin production and able to lay down other important items like tribal squares, oasis, etc. that can also help me delete other buildings like goods and production buildings.
If I am incorrect in my numbers someone let me know.
