OK, sometimes, and not really that often, it can be beneficial to build those "3 tile apart cities"....in special circumstances in the very early game, as land fillers in the very late game. But the ai seems to be on a mission to do this in virtually every game, right off the bat.
Take this screenshot, where I'm invading The Dutch:-
Amsterdam, ok The cap, no comments, Nijmegen absolutely fine, but Utrecht, Its second city? Why? Just why? It seems that if you play on Emp and above, the ai feels obliged to build its 2nd city asap at all cost (really, really not a good move, even with the ais bonuses, on a huge map, when there's lots of land), then in this example, they didn't build another city for AGES.......they had BW really early on, (apologies) you can't see in the screenshot, but where I've put the red blob, would take in the pigs, Clams, and grassland Copper, in a virtually Perfect Grid pattern.
As things stand, do I raze the Holy city, or Amterdam with several wonders? They are completely pointless (placement wise) in the long term (heck even in the mid term), nearly all the useful tiles are shared by both cities.(Nijmegen too for Utrecht).
And this really, really isn't a standalone example, I seem to see it ad infinitum. Use its starting techs etc. bonuses to blast a quick settler out 3 tiles from the cap, virtually all the time.....sheesh...
Anyways, is it just me, or anyone else finding this to be true time after time (It really, really screws the ai in the longterm, it just ends up with two completely mediocre (at best) cities, Instead of maybe one great , at least two good cities).....
Comments welcome (I suspect its just to try and deter me from invading, why bother when I can build a nicer longterm city for the cost of a settler
)
