What?Skyrim which was a genuinely bad game
I don't like Skyrim much, but it won Game of the Year, RPG of the Year and Bethesda won Developer of the Year in 2011 at the Spike Game Awards and the reviews on release where great.
Games don't get ratings for their mods.
Skyrim was so succesful because it has great reviews, the hype was real and the base game was good. Then came the mods and a lot of the playerbase stays.
Bannerlord can have amazing mods, but if new players are not interested in the base game first, they won't try the mods.
Gothic 2, Minecraft and Warband all had amazing mods. But it took so long for me to try them out because I was always thinking using mods was too complicated or cheating.
