Even with its technical issues this game is easily recommended for any rpg fan.
We all have our weak spots for certain games. Even though we hate to admit it, we discriminate in the amount of crap we tolerate from games and its developers.
To me, Fallout and Fallout New Vegas are such games.
Again, the atmosphere of the aftermath of an apocalyptic event is quite compelling and convincing. (for example the lack of a centralized government backing a dollar, makes it a practically worthless piece of paper).
Lots of missions, side missions, individual choices that influence the course of the game, customization of your character, an expansive exploratory area.
Adding all this quantity of game play and the lots of different ways completing the game that goes along with it, these variables are bound to clash with one another.
Still, just like Fallout 3, the fun far outweigh the flaws. Most of it can be sidestepped by saving at regular and separate intervals.
You keep that in mind and you'll have a blast guaranteed.
