I do not what the build calculator to just be a 1 for 1 creation of the game, that just seems silly and pointless.

The issue is the amount of randomness in the game. We can ignore that, but there is a sheer amount of randomness that we cannot ignore it all, like even in the research of what we can build at any given time, which can be randomized by Tome RNG. 

We can preplan things a bit, so we could end up with a percent chance we have the technology each turn and a random percentage value of how possible the build is based on RNG.

We can do Tome RNG, pretty easily, but what about specific resources? Do we care about percentage of getting a magic material. Do I assign a weight and cost for that action?

Maybe instead of actions, I also do plans. Like "Plan to make a city" and "Plan to make a output" when assumed turn times and costs built in.

What's the absolute prototype of the calculator I can make? Just buildings, and ignore: province improvements, tomes, governors.

I DO NOT WANT people to manager turns. The calculator should handle the earliest turn. So obvious actions are, build building, build unit, scout with unit, attack with army.
