I just figured it up,With the units killed here are the resource totals from my cities 26,664,410wood; 14,506,585rock; 21,533,895silver which equals about 805 CF's. my total losses is 5,931,990wood; 4,284,000rock; 3,637,725silver wich equals 235CF's, where for that same amount and not having to sit at the computer as much I have run 175 VP's which would have cost 2.6m wood & Silver and 3.1m rock. so yes CF's are cheaper, but not as fun. I would have to rebuild troops and ships vs my troops growing old while i was looking for something do.
for those wondering this is 610sw,59304sl,21727hop,593ar,4647horse,795char,341cats, 209myth,15252ls,40bi(yes a member of TS attacked me with BI), 7tri,551ft,707rt,0fs10cs
