If you played VH/VH in a vanilla MTW2 game, and played enough turns, pretty soon all adjacent factions would attack you, and your allies would backstab you. You were really in a TOTAL WAR game, maybe fighting 3-5 factions at the same time. I got my ass kicked in vanilla plently of times, and fought lots of battles to boot.
Well, what happened? The mods happened. Instead of the good old 2 years per turn, now we have 0.5 years per turn. Building times have increased to the point of total boredom. All the wusses wanted a campaign AI that wouldn't break alliances, so now that's what we got. Instead of Medieval Total War its more like Medieval Total Peace.

The game has regressed to managing economies, supply lines, and recruitment times.
Darth had a good campaign AI that gave the player and AI factions lots of money. This resulted in a fast paced campaign with lots of battles, where you could forget about the micromanagement. Its out of date now and Darth has left.

I play SS for all the great new units, factions, and map. However I am forced to spend too much time modding it in order to try to recapture that good old total war feeling.
