This is my opinion at least. Fallout new vegas presents a great storyline , great varied quests with huge quests trees and many many ways of solving them , a great non linear sandbox type environment with a LOT of things to do , many dungeons in the form of vaults , great combat system( the fallout 3 type combat system while rudimentary is a lot of fun for me and very satisfying) and multiple endings. In my opinition modern games(i.e mass effect 2 ) dont come close to the amount of choices and moral ambiguity of fn NV and its a game as complex and the oldschool rpgs of the 90´s . The only low point imo are the graphics which i have made more representing of a current gen game with enbs and texture packs. I was overwhelmed with this experience , it feels like a true rpg.
