No.

I don't like the tech tree's being divided into War, Civil, and Magic.  Because we need all three to actually function.  I would prefer different tech trees that could function independently of each other.  Very different in concept.  Meaning I could actually go down one path and not touch the other two and be able to compete, build interesting and powerful armies, have new magic gear and spells, and build interesting and productive cities.  I would like to see tech trees be philosophy paths.  And researching or advancing along a philosophy path would open up new choices in arms, magic, production, etc.  Dividing it up into Civil, War, and Magic just causes me to jump from tech tree to tech tree to get all the essentials needed to even maintain or grow my nation, in reality taking away any real choice at all.

Tell me when you design a game so I can play along, I like this!

1) Can't make a building AND a unit at the same time, and you need to build buildings and grow your towns if you want to WIN (forcing you to ignore units)

It's what's called a Guns or Butter decision. http://en.wikipedia.org/wiki/Guns_versus_butter_model

It's part of the strategic decision you need to make - build your infrastructure, or build a war machine.  If you can do both, then part of the strategic decision is gone.

1) Scrap the civ tree, or seriously rework it to have very unusual technologies.  You shouldn't have to invest research to grow your towns... this only detracts from investing in the War or Magic trees which are the trees that lead to ACTION and FUN.

There are many people who find building to be fun, so please don't universally equate war with fun.  If you prefer expansion through aggression, that's fine, but it's not the only way to play these games.  There are players (referred to as "turtlers") who take the strategy of fortifying themselves in their territory and focusing on development of infrastructure, strategic alliances, trade, etc.  The aggression route leads to an empire whose power is derived from controlling many resources and large populations, while the turtling approach leads to an empire which is small and compact, but whose power derives from its level of development and advancement.  Both should be viable, but mutually exclusive, paths to victory.

Eliminating the Guns or Butter decision eliminates all of this, and forces everyone to play similarly.

I see a few replies to my OP about how "you need to make a strategic choice / guns or butter", and i get it.  But there really isn't anything strategic about this choice... the time for "guns" is obvious, as well as the time for "butter".  Unfortunately, this plays out like how most 4x games do.  You nation build when no one is being aggressive towards you, and you switch to war as soon as someone goes to war against you.  If you are playing any large map with many opponents, that's the strategy...  if you do it any other way, you are just making the game harder for yourself.  This is what happens when you force the player to go building-production+civ-techtree and not allow the player to do more with war/magic/units.  Gameplay is very stale -- you basically just build and ignore danger, until the NPC does something and then you react.  

That is, unless... you have... or you know someone... who has won a large game with many opponents, by going war or magic trees for the whole beginning of the game.  FE will punish you really hard for this and you won't be able to win.

Lord Xia, i like your reply a lot (about how tech trees should be more philosophical and less subject-orientated).  It's obviously a BAD STRATEGY to go 1 tech tree right now... once you clear 1 or 2 tiers in a single tech tree... going to the 3rd tier could be like 30-turns to learn something.  You are better off going to the other tech trees and picking up the little stuff you missed for ~3-5 turns a piece which provide you much much more benefit.  The game ends up having little variety since you learn all the techs at the same time.  I also would like to see a tech tree that you could actually commit to and have it be a viable strategy.

UmbralAngel - i also like your ideas.  how about instead of "middle ground", the third tree could be more magical. How about something like this:

- Wilderness tree - focus on heroes, ranged, earth, air, growth, mobility

- Industrial - focus on units, weapons, armor, production, mines, defenses, fire, earth

- Mystical? - focus on spells (town enhancing, army enhancing, summoning).

All 3 would overlap in many ways... an industrial tree can still cast a lot of spells, for instance. This would be hard to balance... but something like this would be more interesting that what's in place now.  Also, heroes that you recruit can be specialists of any kind... so they will add variety to your kingdom.

I have always been for a two que system (Unit and Buildings) I have yet to hear a good argument against this (and I have heard many)

AS far as the research tree goes well this is pretty standard in 4x games. After all you should only research one tech at a time. Now I would like to see them rework the Tech trees to be independant of each other as is stated by the Dark Lord Xia.
