Northgard vs Warcraft
Northgard
Northgard is a rather unique city-builder/strategy game that allows you to lead a group of Northmen to unknown new shores in hopes of making a life there. Like most city-building games, you'll need to help them set up a home, assign your Vikings to perform various roles, ensure there is enough food to feed the entire village, and amass a small army to help defend your territories from other hostile clans. The strategic aspects of the game may not be obvious at first but you'll quickly realize that new territories that you discover (you don't exactly need to conquer it for this to work) will present new strategic opportunities for your clan to expand or grow, be it new sources for food or a nice place to set up a new trading post. There are many victory conditions as well, so it's not always "kill or be killed" in this game.Northgard offers players a single player experience by playing with AIs with various personalities or with their friends online. However, many players have reported that the game does have a somewhat flawed AI-player relationship. Even if you're best buddies with an AI's clan through healthy trading relationships, their clan members will still attack your people, which frankly feels a lot like a betrayal. It'd be nice to have a tutorial as well.
That said though, Northgard is an impressive game especially if you enjoy a bit of city-builder/strategy game like Valhalla Hills.
Warcraft
Warcraft is perhaps the game that started it all. Here you get to pick from 2 sides, the Humans and the Orcs. Battle for the world of Azeroth as the 2 factions vie for dominance. Play through the campaign for each faction and experience the whole game as you see their stories and leaders develop.Here you have to manage your resources to build your town up and then create your army. Use a variety of units to take to the battlefield including Demons, Undead and Chivalric Knights. Introducing one of the first truly multiplayer RTS games this was groundbreaking for its time and has continued to be a popular franchise.
Take a look at what many consider the beginning and play through a variety of landscapes and see if you can dominate Azeroth.
