Bad North - It's a very simple RTS with nice minimalistic visuals. You get up to four units to defend an island from a viking invasion. Those units belong to one of three types (swords, immobile pikes, archers), and all of them are really simple to master. The enemies mostly belong to the same three types. This leads to simple battles with no deep strategies to master. Just basic logic, put archers up high, immobile pikes in choke points, tell swords to chase enemies. The ai will always run at you like zombies. Done, that's the game.
This simplicity comes to the fore by a rogue lite design where you start over after a lose (there are a few checkpoints), which forces the players to play the same parts over and over again without learning anything or improving their skills, because there isn't much to improve, the game isn't deep enough for that. Naturally, the earlier parts with less units are simpler and more boring, and the game forces the players to play these parts over and over again. There might be advanced content somewhere down the line, but playing those boring early levels was a chore the first time, replaying them is a punishment.
This issue with roguelites pops up a lot. They ape the basic structure of roguelikes without putting in a mechanism for skipping the early game. Nethack allows players to fall into holes in the ground to speed up their decent, Zangband has staircases that lead to floor 50 of 100, accessible right from the start. This allows players to balance the difficulty on their own, so new players usually grind the early levels, while skilled players might opt to rely on their wits and skip straight to the deeper and harder levels. Bad North has neither the skill component to practice, nor the mechanism for skipping the early parts. There are no challenges to chase, or a button to speed up the combat and animations, so it really is just playing the same thing over and over again.
It's a nice game if you're new to RTS games, than one might find it challenging to handle the controls, or grasp the basic strategies involved. I can see how it would appeal to players who are truly new to the genre but I wouldn't recommend it to anyone else.
