Are you kidding me? There’s been continents with professional voice acting and 40+ hours of gameplay added to Skyrim. More than once. Not to mention all the patches and tweaks and balancing and UI adjustments.
Skyrim would have fallen off the top 100 games on steam a literal decade ago without mods and fan made stuff. Instead it’s still ranked like 50th.
Base skyrim isn’t a bad game, but it’s a game that no one would have talked about 2 years after it was released. Instead it’s been 13 years and it’s still ranking around 50th most played game this month.
