i just got Total War Eras... and never had any of the other games except MTW before this.... so my favorites would have to be:
Byzantines (historically speaking, I have always been a fan of the Byzantine Empire) or the
Hungarians (for their challenging position - nothing like a crusade coming thru your lands every few years!)... or the
English (because just like someone said above, I also have a fascination with the Longbowmen - i guess nothing like being able to skewer people from a distance longer than your enemy can manage).
I am looking forward to playing RTW and MTW2 when it comes out.
Does anyone have a faction that they just cannot win with?
In MTW, I have won domination (or massacred with points in achievements) with every faction I have ever played (usually within 150 years or less), except the Holy Roman Empire. It just seems like they have so many provinces with so few troops, so many potential enemies, and very little infrastructure to start with in their provinces (at least in the early era).
