Zee's Properly Timed Eras

Vanilla allows the World Era in a standard 500 turn game to reach the Future Era in as little as 320 turns. Look at the Epic timescale and the World Era is in the Final Era as early as turn 460 in a 750 turn game. This unbalanced pace is terrible for so many of the games systems, which are actually pretty great in a correctly paced environment. If you're anything like me you find it really unsatisfying to see the world constructing jet fighters in 1520 AD. It's not a good idea to make the AI any weaker than it already is, and placing rules that only apply to the player isn't fun. So what do? What. Do. This mod is my attempt at a solution. =+=+=+Overview+=+=+= The reason 320 turns is possible, is because the minimum limit set on each era defaults to 40 turns, which is incredibly low when players and AI are more than capable of moving from one 'Era Layer' of the tech tree to the next 'Era Layer' in well under 40 turns at vanilla settings. Several steps are taken to correct this. The Era (Min:Max) range has been increased from (40:60) turns, to (55:60) turns. Using a Standard 500-turn game as an example again, this increases the minimum Future era turn from (320) to (440) out of 500. Much better. Now you actually get to use the turns in your game... The bonus and penalty for researching Techs & Civics outside of the current World Era is increased from (20%) to (80%) for techs/civics ahead is increased from (-20%) to (-40%) for techs/civics behind In the first half of the game these numbers make it very difficult to break ahead or fall behind. The longer the game goes on however, the larger income-values get and the multipliers have less and less of an effect; which is why the vanilla value of 20% is nearly pointless. This will force the World Era to exist and progress in that (55:60) turn lifespan, in spite of any Civs doing really well/bad because those Civs will find it much harder to throw the world average tech-level out of line.
