If your after more of a challenge this will present it to you.

Compared to RTW this campaign is Hard and slower going. You never know when the next Horde will show its ugly face on your doorstep.

Unrest is a big issue, religious or otherwise.

The Western Roman Empire is itself so weak it practically falls apart like soggy toilet paper before the first Barbarian Horde is spotted over the horizon!

The fact that barbarian factions go Horde on you when you take their last town also adds a whole new dimension to the game... You cannot wipeout a faction with meagre forces anymore when they get 5-6 full army stacks appearing from nowhere.

RTW had its flaws but this has addressed them as best as can be done in an expansion.

For a simple expansion set, I think its done quite well.
