Games like Last KingdomWatch
Are there any games like the last kingdom? Where you can raid cities and take over?
If you're looking for something more with action-forward gameplay, Kingdom Come Deliverance has raid and siege sections buried in a very in-depth medieval RPG. Assassin's Creed Valhalla also has a heavy focus on raids, but it's a Norse story in the vein of Vikings along with everything else that comes from being an AC game.
