I recently ran a 4 session DnD one-shot (online 2hrs each) set in an as historically-accurate-as-possible viking world. I limited players to only 8 classes with limited magic, which had to be flavoured to be norse-inspired, but it felt too limiting. As this was a One shot I wasn't worried about severely limiting player agency and choice, and tried to explain to the players to think of the game not as Dungeons and Dragons Vikings, but a Vikings game using the DnD system; which got me thinking. Are there any other systems that would be way more adaptable to a non-mag viking world? There's been a few reddit posts i've seen mentioning the likes of Zweihander, RuneQuest, etc, but the posts are years old now.

I'd only been introduced to DnD around a year to this day, and since been madly addicted, to the likes of total homebrew world creations - so I don't really like the idea about re-learning a totally new system already, but if something is suggested that's fitting and relatively simple, I'd definitely be keen to check it out.
