It didnt take me 2-3 months, albeit I used the healing axe and left my computer running thanks to a reactor fueling itself and another with a laser drill.The quests are aimed at SSP. The aprox time line is 2-3 months for single player. It is not an FTB map. And the "old" map has nothing to do with Ag Skies.
EMC was a thing of the past man, I loved it myself but I personally love this much more, all you needed to do was set up a tree farm then you're set for anything you want. Then it was just getting one of those glowstone generator thingies (cant remember, so long ago now)Still a good map that's close to the heart of "Feed The Beast" (using it mainly myself as a learning tool for some of the newer mods), but I do prefer the old map in 1.2.5 days with EE2, where you had to use vanilla systems to get your EMC income, and convert that to resources you needed, figuring out what you could actually make, and then figuring out what the Quest Rewards can unlock for you.
As what @Jadedcat said, this isnt an official FTB map, not even a FTB map at all and has no correlation to the old ones. Its based on a in game story if you read it, hence in my world I followed the story and actually rebuilt the land as sad as I was.... I finished the map in less than a month and then spent another month going with the story line, something which you couldn't do on the old maps, hence why its awesome!
