If i do this search Valheim is first and For Honor third, maybe it‘s related to the games you own ;)

That's funny. Isn't For Honor just an arena game for a myriad of classes including a 'viking' class?

...in "Vikings" Term Search bar

That's like putting Animal Crossing at the very top of the search list before other games like Cities: Skyline and SimCity, because we searched for city building.
