There are so many game expansion mods out there that promise to add hours of content, but which ones actually deliver? I've installed some that were buggy messes and others that felt like they should have been official DLC. What are your favorite game expansion mods that genuinely feel like they could have been made by the original developers? I'm especially interested in mods that add meaningful story content or new gameplay systems.
For game expansion mods, the Falskaar" mod for Skyrim is legendary. It adds an entire new landmass with quests, voice acting, and everything. It feels like official DLC. Another one is "The Frontier" for Fallout: New Vegas - though that one had some controversy, the scale is incredible. These game expansion mods show what happens when modders have years to work on a project.
I'm always cautious with game expansion mods because they can break with game updates. The best ones are for games that are no longer being updated, like New Vegas or Skyrim LE. Project Brazil" for Fallout: New Vegas is another amazing game expansion mod that adds a whole new story. The quality of writing in some of these mods is better than what you get in some AAA games.
The Long War" mods for XCOM are the gold standard for game expansion mods in my opinion. They don't just add content - they fundamentally change and improve the gameplay systems. The developers actually hired the modders to work on XCOM 2 because of how good their mods were. That's when you know you've made a game expansion mod that's actually worth installing.
