Quite original for an RTS game. It reminds me a bit of something Stronghold because of the way population and combat works. However, base building is completely different since there are no supply lines and such.
People call this a 4X game too which is kind of true. Obviously it can't afflict you with a case of "one more turn" when it's played in real time, but the upside is that you can complete a game within a single hour, and that's a decent trade-off.
I would say the way that the Viking theme is characterized is one of its weakest aspects, but the main campaign is fun nonetheless. I found the writing to be a bit dull, but it's elevated by some good voice acting.
As for presentation, I don't particularly like the aesthetics of the game because they look a tad generic. I could say the same about the music and sound effects, which is kind of bad for an RTS which tend to have very memorable voice lines and such. For as good as the voice acting is in the campaign, units during skirmishes communicate exclusively through grunts.
Apart from multiplayer there are skirmishes against the AI and conquest mode which is generally harder and adds some random elements to keep things fresh. I think that's great for singleplayer content.
Overall, I'm left with positive feelings about Northgard. To me, it's not the most memorable game, but it's fairly original and quite fun nonetheless.

- 60% Warcraft 3, 35% Banished, 5% Banner Saga I was surprised just how much I loved this game. It can feel too hard at first, but that just means you have to get used to the ebb and flow of its particular strategy. Stick with it and you'll feel that same pleasure you got from Warcraft campaigns back in the day. Add on that randomized single player maps, a slew of achievements, and a small, but present, online community and you'll find yourself coming back for more. My only wish was that the campaign was longer!
