Hi,
On normal speed, which is the "usual" turn to get to the vital steps ?
For example, which is the required turn for the NC ? For Education ? How many science should I be generating by turn 100/150/200/250 ? Assuming I didn't go for early domination.
Thanks in advance
There is no "required" turn, and any guidelines should vary depending on difficulty level, starting Civ, map, whether you're a big re-loader or not re choice starts, and, most importantly, how selective your memory is/how full of crap you are.
My personal guidelines for pangea are:
NC no later than turn 95 (4-city start), turn 85 (3-city start)
Education by turn 120 at a minimum, maybe 115. (Sometimes, though, you get distracted by early aggression.)
By turn 160 I'd like 220+ bpt but have survived with less
Scientific Theory somewhere turn 170-190
By turn 200 I'd like at least 500 bpt, 600bpt+ may be doable if you haven't had to go to war, if you have at least one nice-sized city next to a mountain.
Capped bpt at around 1000+, shortly after Plastics, of course.
You can do better than any/all of these with a great worker-mugging start and/or an OP civ (Poland/Shoshone/Maya, maybe Korean/Babylon in this case), of course. But with a standard Civ on a standard map with a standard start where I haven't been able to do a ton of worker-stealing, I'm happy with the above.
Note that the numbers I have above are mostly "Do at least this" not optimal targets. I hear "Education by turn 105" thrown around a lot, and while I've done that (once or twice), it's not something you should pretend you'll be able to do very often (unless, again, OP Civ/start/etc.)
EDIT: I will add that my move from Emperor/Immortal to Immortal/Deity would not have been possible without setting an earlier target benchmark for NC, combined with liberal worker-mugging. It's amazing how important those two things are ...
