It has been nearly eight years since the release of Blizzard Entertainment’s mega-popular computer game “Diablo II.” (Blizzard is the same company that created “World of Warcraft” and “Starcraft.”) Now, after an expansion, numerous revisions and a whole series of spinoff novels, the next chapter in the series has been revealed.

And true to Internet form, some people are already complaining. Addressing them: The game you’ve been wanting for nearly a decade is finally announced and all you can do is carp about how the art design isn’t as dark and dank as you’d like? Seriously? Geez, get a grip.

Anyway, the rest of us “Diablo” fans are looking forward to another habit-forming adventure in the demon-infested world of Sanctuary. Over the weekend I reinstalled my copy of the game at home and started playing, and was quickly reminded why it’s so compelling.

On its face the game doesn’t sound that special: You create a hero, selecting from several different character classes like Barbarian, Necromancer and Paladin, then journey out into the world to kill monsters, pick up the loot they drop, move on and repeat. It’s a simple formula.

What makes “Diablo II” work so well is its nearly infinite replayability. The base game has five character classes; two more were added by the expansion. Each of these classes has its own specialties, with a variety of abilities divided among three distinct skill paths — a Druid, for example, can learn skills in Elemental, Summoning and Shape Shifting disciplines.

As a player player monsters and finishes quests he or she earns points to spend on skills in these trees, but there are only so many to go around and they can’t be regained once spent. How a character’s skill set is customized is as important as the weapons they wield. Add to this a huge array of equipment and items, area layouts that are randomized each time you start a new game and an interesting story, and you have a recipe for a killer time sink.

The complete “Diablo” package is pretty cheap these days —it can be found for as low as $30 or so online — and with the sequel in development now would be a good time to check this classic out.
