I never get the hate for Total War games in these forums. Aside from the usual trolls "hurdurdur DAE Total War shuksh XD" posts, they are as fun as Paradox games in a different way personally.
It's all about depth on campaign VS depth on field battles.
I agree man. Medieval Total War was the last one that had family trees IIRC? I don't remember them past Medieval.
Total War Attila was the last large Total War game to support family trees (if you discount the side-game Total War Britannia released this year, also featuring full family trees). Also, Shogun 2. And now Rome 2.
And RTW and Medieval 2 which actually created this feature close to how it is known today.
Also, Empire had a family tree feature too, but it was hidden behind the UI and required a mod to see...but it was there (it handled succession crisis and wars and such). It was also rigged to be historical for most nations, so for example King William III or Emperor Alamgir would die precisely near their historical death dates...and would also be succeeded by Anne or Shah Alam I instead of randomly generated monarch for example.
Unlike your claim, Medieval Total War didn't actually have a family tree. After first two rulers all you had was randomly generated sons and daughters each generation, of which either your eldest (as Christian) or your most capable (as Muslim) male son would become heir. Shogun 1 Total War, the very first TW game, also worked the same way. Much like EU3/EU4, but with actually more than one heir.
