Having all three of the happiness resources that require only Mining to use, all within a short distance of the start,
Uh?? I'm sure I only had gold and gems. Where was the silver?
Have to admit I thought the opposite to you: I felt happiness resources were a bit on the short supply. Sure, we had gold and gems to get us through the very early game, but other than sugar, we didn't have access to any of the calendar-enabled resources that you'd normally rely on when your cities start to hit size 6-8.
On the other hand, the huge expanse of resource-barren jungle north and west of our start is not very pleasant at all. But this is Diety level after all.
That may have been intended as a helper too. The AI isn't very good at settling jungle, so that area may have given us more places to settle that Hatty would've avoided - and with some clearing and cottaging, a lot of that land is quite lucrative long term, even though the lack of (especially food) resources there is a bit of a downer.
I certainly agree with you though to the extent that Ainwood must've planned the start to make it easier to build a fair initial empire without getting boxed in too early. Only problem is that made it harder to quecha-rush. Given that at deity level, the consensus seems to be that you need to do some conquering to get ahead, I suspect this map may turn out to have been harder than many typical deity maps to actually win (other than by culture), even if it made it easier to survive to the AD years with some sort of empire.
