That is the wrong question.
Specialists do not need to be exciting for wide empires. Wide empires do other things.
The question is like saying: "how could we have Tall empires still have massive amounts of territory"? It's the wrong question; if you want lots of territory, don't play Tall.
I'll disagree here. Tall is the definition of "small empire with huge cities" so Tall with territory is not "Tall".
however in the definition of "Tall" there is not the wordings "no village". That is a consequence of game-mechanics that make village worthless for Tall ; but it is not mandatory.
What I think Thal is saying is:
"you want to block a gameplay to a gamestyle".
you say that the paradigme is between "village don't go with Tall" and "the choice between village and farm becomes moot".
for me it's like saying (on the graph) Either I'm extrem left or I'm extrem right.
You are forgetting the middle ground.
And here I disagree with you and agree with Thal.
(however maybe the solution proposed is not the good one, but the aim is IMO worthwhile).
why do you WANT to BLOCK some choices and link farm / specialists to TALL and village to Wide ?
is conquest linked only to WIde ? or can Tall do it ? or is wide limited only to conquest ? or can it do other things?
I don't see why
goal (victory), strategy (tall/wide/warrior) and gameplay (village / farms / specialists) have to be linked.
Sure, some combination might have synergies, but you are making some combination MANDATORY (wide almost never use specialists and Tall almost never use villages). and that's not fun.
Sure, if you could have both farms and village for all, it would be boring at all times you would have specialists + village everygame.
but currently you are advocating either WIDE + village OR Tall + farms.
so instead of a multiplicity of choices you want the game to be rigged to 1 choice :
wide or tall ?
instead of wide or tall ... + will I boost my farms/specialist or will I boost my villages to complement my wide/tall strategy and while one combination is generally better, the other situation might be situationnaly better (depending on map, neighbourgh...Etc)
IMO, it would be great to enable farm OR village for either Wide or Tall.
such as being able to develop villages for TALL (to the detriment of specialists) and being able to develop farms/specialists for Wide (to the detriment of villages).
Those would open new ways of playing wide or of playing TALL.
So sure, normally farm-specialists is the TALL way... but why not open a viable way of playing TALL that is based on villages and whatnot
instead of farms ?
I have no ideas on how to attain that goal. But Thal is trying, while you want to keep the statu-quo.
IMO, it would be better if, instead of keeping your position, you tried to understand Thal's aim and propose "better" solutions... or solutions that might "alleviate" your fears.
some random ideas (IMO they are not good ideas but might go into the direction of the "middle ground"):
-why not have the "tall" civic on villages have town give a specialist to nearby city but have the town roduce less food / production (or reduce food in nearby cities/in nearby farms) (or give 1 unhappy).
(so suddenly the town might become another way to get specialists, rewarding the TALL that used a village.
-why not have the "wide" civic on specialists give a +100% to GP yield instead of free specialists. Thus, your 1-2 city that was focused on specialist is boosted and that civic serves to compensate your one weakness : low GP generation as "wide have no interest in specialist as they are un-useful in small cities".
EDIT : well it seems Tarquelne said it much better than me.
JohnS has also some good ideas
