I thought the game was just absolutely amazing, exp is much easier to accuire then Fallout 1, also theres more to explore in the game, leaving more for the player to go through for quests and tasks.
There are also a fairly increased iventory items for the player to gather and make use of, skills seem to come in hand more than in the original Fallout.
I simply loved this game and i say its a was a great addition to the fallout series when it first game out.
