Hello. How do you all handle timelines in fantasy games. Especially with magic, gods running around, and more races? Do they rapidly progress from stone age into bronze and then into iron and medieval? Do you skip some levels? I've looked at many homebrew timelines (on websites) and some had them divided into ages (though they were ages divided by wars and cataclysms). Most of the timelines just had wars, nations rising and falling, heroes, magic, etc. I was working on my timeline for my homebrew and was stumped. How many years do you think it takes for the civilizations of your world to "step to the next level"?
