One of the major criticisms or the original Diablo was the NPC's. They remained in the same spot: they never handed you weapons or items, nor did they join you on your quest to kill Diablo. In Diablo II players will now be able to hire NPC's to join your quest through the dungeons. They will require a lump sum of money (or perhaps other items), of course, though their help will surely be invaluable. Town NPC's will no longer be stationary as they were in Diablo. The blacksmith, for example, may walk out of his shop periodically and take a stroll around the town.

You will also be able to enter the shops and have conversations with other NPC's. We will also be handed weapons from now on, so unique items will not be thrown on the ground. There will be different merchants throughout the different towns. With more specializing in certain items like potions, elixirs and the sort.
