I dunno i don't have a turn time or againg issue in MTW 2, i've had about six emperors, all died of natural causes, we're in the fourth generation, i'm about half way through game, so i'll end about eighth or ninth generation. I have experienced gothic knights, gunpowder, and egypt is still most advanced lol. I like the turn system and aging. I guess if you figure 3 generations per 100 years tho, and the game goes 5 centuries, you should have 15, I guess if you want more diversity you can but i like my leaders to at least age and make a name for themselves.
