I remember playing Skyrim at launch. The very first mod I downloaded was to restore Esbern’s voice lines; an npc critical to the main quest early on.

Bethesda forgot to reference his voice lines in the script, which broke the game.

Skyrim was extremely interesting when it was new because there wasn’t anything quite like it, but now there’s a lot of games that are like it and it’s not that great and it’s just kind of aged with mods or whatever
