4X,Rome II better then original,looked bad...twilight zone.Stop posting total vomit.
Biggest decline was the free movement 3d campaign map,all problems come from there.The AI can't path,defend cities,move armies and coordinate attacks properly since Rome.OTOH The battle AI is identical in all games(except Empire,where it was totally broken),it just takes the high ground and waits,if attacker and have cavalry will flank you,sometimes will bug itself and just stay frozen,in all of them from original Shogun to Atila.Sieges are always coin flip where you prey it does not bug and while attacker just sits frozen again,or bugs the gates,or the ladders,in all of them from Shogun to Atila.If you think in some of them the battle AI is better you are wrong it's constantly mediocre.At lest pre-Warscape there were big battle AI mods.
If you want scripted story Total War try Third Age campaign mod and if you like it more then kill yourself as that goes against what make TW/Paradox open map ,do what you want design so alluring.No they don't need to scale down ,they need to make everything bigger,more grand as all decent mods are doing every fuckin time->more complex recruiting system,more provinces,more units,more cultures,more religions,more trade,more more more.Just ditch the fuckin 3d map.
