i think this is on par with the base game in terms of how fucking good it is. it's darkly comic all the time, it echoes b-movies of 50's and 60's hollywood in a way that doesnt alienate the player, the new guns and laser weapons are cool, the locations are fun to explore, and its not overbearingly hard. old world blues is easily my favorite dlc for any videogame ever made. i look forward to it with every single replay of new vegas, such a blast!
