Dungeon Keeper vs Northgard
Dungeon Keeper
Dungeon Keeper is a somewhat tower-defense-like strategy game that allows you to build your very own dungeons, staff it with a plethora of demonic minions, and set off to raid other people's dungeons to win some sweet loot. Play as a ruthless dungeon keeper as you do your best to stop these pesky adventurers from stealing stuff from your dungeons. Get creative and devise the most painful ways to deal with these hapless heroes with the many tools at your disposal like traps, hordes of demons of all shapes and sizes, and more.The PC version of the game also has a special multiplayer feature where you can play with up to 4 of your friends and challenge each other's dungeons for the rights of being the best dungeon keeper. Of course, the reworked mobile versions are already multiplayer games whereby you'll get to raid anyone's dungeon and everyone will get to raid yours.
If you liked games like The Mighty Quest for Epic Loot, Dungeon Keeper is definitely right up your alley. If you want to play the classic version, then you can get the PC version; if not, you can give the mobile game a try instead.
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.
