I thought Rome 2 was a lot better than Attila after it got fixed and worked on. Attila was kinda meh to me. Plus super annoying campaign mechanics. Felt far too much like needing to rush the campaign. I always prefer expanding slowly. Maybe that isn't a problem for you, but you REALLY have to rush the campaign and blob out quick in Attila.
I'm one of the few that like Rome 2 (and now Warhammer Total War) better than the older versions. Medieval 2 has epic mods and all, but the factions are so limited...it feels too empty and barren. When I play Rome 2, the world feels full of life and other factions. Going back to Rome 1, even with amazing mods, it really feels like going miles back with limited faction slots. Warhammer total war is the same way sorta, but that is because its missing a lot of races/factions
If rome 1/medieval 2 didn't hardlock the amount of factions modders could add to the game, I'd think they were a lot better. Too bad though that you can't mod more factions into the game, without very quickly hitting the hardlock the developers put in place. Its one reason I like the newer total wars, and games like EU4 and CK2...tons and tons of factions to play as. And if they are locked (like in Rome 2), you can just mod it to unlock all of them.
As an additional post edit note
The combat in the older Total Wars is nowhere near as good. That is obvious because they are older. But a horse charge feels like they ran into a bunch of pillows. Dunno how else to describe it. In the new total wars, there is mass impact, feels like an actual charge. Combat animations vastly better. Yeah its because they are new and modern, but going back to the old combat is incredibly hard and far less satisfying.
Anyway this thread is about Attila of course, but some people are talking about other Total Wars. Even though I like Rome 2 a lot more, Attila is still better than how the older Total Wars were. And playing as western roman empire is like playing a hardcore survival strategy game. Its by far the most faction in Attila.
