Is Diablo II for PC a game that's worth buying?

[tbone_of_07]

I was at the store today, and I saw a bundle for the game Diablo II for PC. The bundle had Diablo II, an expansion pack for Diablo II, and a walkthrough of the game for 40 bucks, which I figure is a good deal for all of that stuff. I just want to know: Is the game any good? It looks like it would be, but I've never played a Diablo game, so I don't know.

Also: Does anyone know if the game will run on Window Vista?

Thanks to all who respond.
