The only thing preventing me from giving this game something more than YES is the poor optimization that requires an unreasonable amount of mods to fix. If you have the willingness to mod a game, and you also want an RPG adventure in a post-nuclear world, then you owe it to yourself to play this masterpiece. The story is interesting and enticing, the humour is on point and the side quests are prone from sounding boring at first before creating one of the most memorable side stories in the whole series (The quest 'Come fly with me' is a great example) New Vegas gives the player so much freedom that no character is protected by plot armor. You can kill major characters (generals, politicians, leaders, business people, etc) and still progress the main quest. The game also questions the player on ethical and moral questions. Moral questions are not as simple as the "do you want to genocide or not?" that you see in Mass Effect or the "do you want to nuke a town or not?" that you see in Fallout 3. Decisions force the player to think about what decision they will make rather than just choose generic good guy or generic bad guy.
