Techs can be researched only if the civ meets conditions for them.
It is that I see a horse first, and then I can learn Horseback riding...
It is that first I have a hill, then I can learn to mine it...
How could I learn Sailing if I don't have a coastal city?
Etc.
(Another condition is to have prerequisite techs, but that is already in the game...)
Naturally, the tech-tree needs to be restructured, techs renamed or added, like for modern ships to be in the ship side-branch,
and there will be also side-branches for those that need resource, but it can be done...
Separate branch for air units, too (they need oil).
The conditions (prereq. techs not listed) as signed as "C". They are a minimum that must be met.
I also list conditions as "SC", Speeding Conditions, that are hard to meet
and speed up learning of the given tech... say, e.g. with 15% bonus...
It could be that both "C" and "SC" are in the game, or only "C" or only "SC"
(I might put up here a poll on this...)
(I set techs that are in main branches of the tree in bold (they need no resource))
I hope SCs are to be in favour for the smaller civs...

I attach a tech tree (12th of November: v2) where bold techs are for the main tree.
(Under the techs you can see pre-techs in italics)
I much welcome suggestions, improvements, corrections, opinions...
However, it would seem that it would be possible to be severely hamstrung by geography. What if you don't have horses nearby? How do you continue along the path that horseback riding is on (assuming it is on a path of some sort)?
Perhaps a compromise between the two would be that the conditions listed simply gave a bonus to research, rather than being imperatives to any research at all.

Some of the conditions can be met easily and logically, if your civ develops.
I see no problem with that.
Those conditions that are tied to a resource would be for techs that are
to be placed on a side-branch, so that the civ can still go on the main branch...
Nice! Love it! For our religion mod we were going to have polytheistic gods that were relevant to what you had access to, for e.g. no mountain god if you don't know of any mountains near your cities.
Having this idea for techs is really interesting.
Writing = meet a Civ though? ;D that would make island maps an odd experience science-wise.

Lemmy, I give it to you free, this and every idea I have and will have
Just make them a mod so I can play with it, and let me contribute with further brain work...
I don't think you should tie technology to resources. If you're on a continent without any iron at all you shouldn't have to wait for navigation to progress. Can you even get to navigation without iron and horses?

I approve! Perhaps it might be useful to outline the 'maintstream' techs (techs that don't require resources/ideas/goods/etc.) so we can see how a player stuck on a 1 plot island with no friends would develop. Slowly and very lonely, obviously, but what about tech?
