No It's a complete board game that includes all you need to play right in the box. There is an additional expansion for the game that is available which adds more fun to the game but isn't needed to play. Lots of fun hope he enjoys it. If he does check out the expansion Scoundrels of Skullport.

There are 12 different lords you get to play so your end goal is different every time, but the game play is the same.

There is no solo rules built/included with the game, but there is a solo variant on boardgamegeek.com (boardgamegeek.com/boardgame/110327/lords-waterdeep/files). This is a user-made variant. Not sure if Scoundrels of Skullport expansion is needed for it, however.
