The Diablo series is one of the most action-packed, loot-heavy, and (let's face it) fun ARPGs a gamer could possibly play. With a varied cast of playable characters, a plethora of destructive weapons, spells, and strategies, and enough treasure to make Smaug's eyes pop out, there's more than enough to please any rank of player.
That being said, even the most explorative of dungeoneers run out of places to explore and monsters to mash, as impossible as that may seem. Thankfully, Diablo provided an RPG template that was easy for other developers to give their own spin on the formula.
Dungeon Hunter Series
This series featured on smartphones and tablets is essentially a "my-first-Diablo" video game, but that's not necessarily a bad thing. The series got deeper and more developed as time went on, but it's so easy to pick up and master. It might have basic classes and weapons, but there's more than enough hack-and-slash action to be had by all players. It's not a perfect game by any means, but that doesn't mean it isn't fun.
Bastion
What Bastion lacked in character classes and loot it certainly made up for in action, storytelling, and gameplay.
Players won't find barbarians, wizards, or demon hunters here, but they will find The Kid with his armory of weapons and skills to cater to different playstyles, a shifting and changing environment loaded with bunches of baddies to bash, and a narrator with a smooth and silky voice to tell the tale. It certainly has some serious presentation skills.
Darksiders Genesis
Although worthy of a James Gunn movie. Fun, fierce, and distinct, to call it a clone would be an insult.
Heroes of Ruin
For players who owned a 3Ds and didn't at least try Heroes of Ruin, they missed out on possibly one of the greatest action RPGs on the system, and they should be heartily ashamed.
This game feels like a beautiful hybrid of Final Fantasy and Diablo III, and it offers unique spins on ranged and melee-based combat that any RPG fan will adore. The levels might be a bit linear, but the characters and combat are unique and enjoyable.
Dragon’s Crown
It might be a side-scrolling beat-em-up, but it has just as much loot, environments, monsters, and boss-fights as its devilish counterpart. Where Diablo relies on the grimdark world of Sanctuary, Dragon's Crown uses traditional Walt Disney that caters to any RPG fan.
Gauntlet
Diablo definitely pulled a lot from the OG dungeon-crawler, Gauntlet. So it makes sense that the game would go full circle after vanishing off the map for years. The 2014 remake of the arcade classic is essentially the same title, but with a much-needed Diablo-esque upgrade.
There are massive hordes of monsters and enemies, piles of gold, and encounters that will have seasoned players in a button-mashing frenzy. A bit on the basic side, but it retains the arcade-style action that made the original a classic.
Sacred Series
Though they might vary in of content, the Sacred games are great for anyone climbing off the monster-slaying high of the Diablo games. The gameplay is remarkably similar, and players will still have the opportunity to pit their heroes of choice against demonic forces using magic, melee, and other abilities. The games are all rich and varied, even with a side-scroller and Gauntlet-inspired title in the mix for good measure. Both series are certainly a perfect pairing
Wizard of Legend
The other classes might have been nixed in favor of the magic-, players will no doubt feel mightier than Merlin, Gandalf, and Dumbledore combined in this magic-focused dungeon-crawler.
Instead of slashing swords or charging in with large blunt weapons, players will tear their way through dungeons using a variety of devastating spells. Sling bolts of elemental energy, hurl lighting blasts, and set hordes ablaze with magical fury to reach the end goal. Simple, effective, and action-packed, what more can a wizard want?
Titan Quest
If Diablo and mythological offspring. To say that Titan Quest would be Diablo with a Greek epic coat of paint wouldn't be untrue, but there's much more to it than that. There are many various ways to play and build one's character to make them the ultimate hero of the ancient war.
Torchlight Series
The Torchlight games are the perfect complement to Diablo, though they might come wrapped in two totally different packages. The bright and colorful adventuring seen in the former definitely clashes with the dark and demonic slaying of the latter, but the explorative gameplay and massive amounts of minions and monsters remain the same. It's great for younger adventures looking to try the formula, as well as seasoned slayers who need a little magic in their life.
