Huge disagreement. You and I have drastically different play styles. 150
translates to 3 HAs, 3 Catapults, 4 Sword, 2.5 Elephants, or 2 Trebs. If someone wasted the time putting 3 or 4 markets (or more!!??!!) in their cities that could easily add up to 450 - 600 +
.
That translates into 10 Elephants, or 16 Sword, or 12 Catapults, etc, etc. And that translates into 3,4, 5??, etc, etc more captured cities at an early date which snowballs into a much larger and stronger empire.
Don't you realize that by the time you actually built the Market and then
grew to your new happy cap the person that whipped/chopped all those units would already have conquered all those new cities..........but more than just that, they would already be whipping/chopping more units from those captured cities.
By the time you were actually ready to start making units from your new market/bigger happy cities I could already have 6 or 7 new captured cities. And once you get those Markets how do you plan on getting units? If it's slow building them that will take ages and ages by which point I could have 10+ cities by the time you have your 1st big way of units.
And if you aren't going to slow build your units and plan to Whip?, then what was the point of building a Market in the 1st place?
Even w/out CRE, if you have a forge a Theater is basically a 1 pop whip or chop. That's really quick. And in most cases you don't even need to add a Theater until you've already done quite a bit of whipping. This works great because it doesn't slow down your initial build up of troops. And as already mentioned before, Theaters and the culture slider will allow you to deal with happiness whichever route you go (more whipping or stabilizing). Oh, and as mentioned above GT!
So there's cheap warriors, luxury resources, trade, forge, theaters, and Civics (+1 units/+2 Barracks). So in most cases, why in the world would it make any sense to get that Market?
