The Game series of Diablo is a classic dungeon crawler slash adventure RPG game.

It resolves around killing the demons of hell and later even angels of heaven from taking over sancturary the Diablo universes version of Earth

It's major draw is the loot you could get from killing monsters which is what gives the game an addicitive effect on the people who play it they want to get the best loot possible and will play for hours or days to get it

Also the game is for its class customization and freedom to make your character how you want to make them

A negative to this game would be at least for the first game is there only being three classes the warrior, rogue, and sorccer who each only had one special skill and could learn others but through scrolls which downgraded the uniqueness of the characters because all three the characters could have all the spells so everyone would be the same in a sense.

Another negative is in Diablo 2 when leveling up your character you had to spend a single skill point on one of your skills from three trees of skills which caused many players to consider their choices before choosing their skills knowing that they could only redo their skills by reseting their points once so they had to make certain that every decision they had with point distribution was planned well.
