I’ve been so disappointed with this one I don’t think all the DLCs in the world can help. I’ve been a fan of the franchise since the original, and liked New Vegas best overall. It’s lost the RPG/ gritty post-apocalypse realism heart of the original concept that made it great and it just feels like another boring game. Mount and Blade Warband (Viking Conquest DLC, or the many mods) is a great example of a truly sandbox game that runs from strategic to tactical level that is never boring, yet is a fairly realistic simulation of the genre (medieval warfare) with enough RPG elements to be immersive. Wish Bethesda would move in a similar direction instead of the bad FPS arcade style shooter.
Try survival mode yet?
