This is just a small feature that would i really would like. As it is right now, all eras are 10 techs long. I like how it constantly makes you reevaluate which tech you need now and wich ones that you can live without. But giving us the ability to adjust it, maybe just from 5-15 techs, would allow us to make games more personalized. Don't like the stress of picking which techs you need now and which you can go back and take later? Increase the number od techs, then this problem disappears. Want to really agonize over every single choice and constantly be on the edge of your chair? decrease it and advance through the eras at lightning speed. And while we are at it, it would also be nice to have a slider to adjust the research pace, so we could have a game where production could be standard and research costs would be slow or endless. I know this would throw balance out of the window, but it would make the game more customizable and increase the replay value. 

What do you guys think? would this make the game better or worse for you?
