Just because a point is short and obvious does not mean it's empty gesturing or speculation. In fact, it really points more to your stubbornness and ignorance when it's THIS short and obvious, yet you still cling to your argument. You can't admit that 1UPT (primarily in a case like this where Units and Cities are the same size, and these tiles being too large for a "tactical" feature) is the root of many problems because you've attached your argument to it now, and admitting it now means you've been defeated by a stupidly obvious point. Can't have that.
It's simple.
That's it. At least concerning units. Building Hammer costs... and Gold/Building Maintenance... are similarly limited for the same reason. Low yields relative to Production costs.
- If they had wanted, they could have made units quicker to produce.
- They did not.
- So they are not.
- Why not?
- To avoid breaking 1UPT.
- Except on Deity, where it's broken anyway due to production bonuses.
Everything else you're saying is just camouflage to avoid admitting you are wrong.
If long building times of units are due to 1UPT, why are constructing buildings so slow also? And why is the rush buying so efficient? While this "1UPT leads to low production/flat tile yields" -theory has been mentioned numerous times, it's not plausible at all.
