Better!, though admittedly I don't really remember the first one that well. This one is just very... Napoleonic, so if the musket era is something that intrigues you, it could be right up your alley.
It stills has some of the basic resources that you need to mine, like wood and stone, but they quickly become irrelevant because there's relatively little base building, unlike other RTSs. From then on, you need to conquer villages, which provide one of the following resources: food, needed to feed troops and create them; coal, used to fire guns; iron, used to fire guns and create troops; and gold, used for troops. If you don't have enough coal, your troops won't be able to fire. Thus, village control has strategic importance, as do the supply lines back to your home base.
There's maybe a little less unit variety, but each unit has its purpose. The combat implementation lends itself to some really cool tactics. It's unit regiment based (moreso than the first one, as far as I can remember), with roughly 90-180 units units per regiment and things like regiment formation and digging in really being important to keep morale up, moving effectively, defensive ability, etc. You also have cannons, artillery, cavalry, etc, all of which are good for different things. All the regiments have experience, meaning their maximum morale increases. Battle-tested regiments will thus be much more valuable than regiments fresh off the barracks!
I'd say this video gives you a nice overview:

But it makes for some faster battles. I forget what the story campaign is like... it's less free-form, but I think it gives you more of that strategising.
All in all I think it's a super solid title if you're into musket warfare and are prone to liking Cossacks-like games!
