Some suggestion: I think Tech tree would be revised a bit, some technologies appear too early, too easily without prerequisites. For an example, Mine warfare appears very early, in Rennaisance, though it's an industrial technology doubtless.
We try hard to maintain historical accuracy, to the extent that is possible. If you notice the tech tree: Mine Warfare requires Gunpowder. Gunpowder appears in the Renaissance era and is required to research Mine Warfare. History records one of the earliest uses of mines was in 1689, when French forces blew up the towers and walls of Heidelberg Castle in Germany.
Resuming, I have the impression there is access for too many techs simoustaneously, without other than should be necessary. I'll play a bit more, to see if i can be more concrete (Mine warfare it's the most obvious, it's the first that I've encountered, recently started Renaissance era)
Simoustaneous access to many techs. Hmmm. What this means is you have a lot to choose from at any one time. Correct? That is exactly our intention, with the development of OGI: Lots of choices. In fact, you must make many strategic choices throughout the game. Do you go for a religious tech or do you research agriculture? Do you construct a building or do you train a new unit? Do you build a settler or a Wonder? Do you build a ship or an aircraft? Do I want more research or more gold? It's all about making choices. ...and we want to make sure you have a lot of choices, when you play OGI.

Anyway, I understand what you say, you can choose to play researching technologies with somewhat historical accuracy, or have a narrow-minded militaristic research or so
And i'm not yet got Modern Era, but I don't even want to think that I'll find my Main Battle Tanks flank-damaged by an horde of enemy horse archers... ![Pissed [pissed] [pissed]](/images/smilies/pissed.gif)



I suppose you want to make it a bit like Civ1 spirit, but IMHO this means to downgrade the game a lot... If I remember well, even vanilla BTS had paved roads, so I cannot understand why you deleted these features 





My suggestion is to treat them like PARATROOPERS OR STATIC LOADED TROOPS (AMMUNITIONS). The concept it's much more simple and much more realistic. This should work as this: 
Sorry, I'm completely accostumed to mods (never play vanilla BTS from ages) and nearly all of them add paved roads, highways, ecc.
:
I believe I have a possible solution, but it needs testing. Add the following XML change to all 6 mine units in the CIV4UnitInfos.xml file:
but as for realism, I figure you wouldn't know how good an enemey's musket was until he started using it against you.
Can be airborne, ship-borne, artillery launched.... Absolutely realistic !!!!![Pimp [pimp] [pimp]](/images/smilies/pimp.gif)
