17 The Hitman Trilogy 
The new Hitman trilogy ?also known as the World of Assassination trilogy Diablo IV Items?released in 2016, 2018, and 2020 respectively. The games functioned both as a sequel and a reboot for the series after Hitman: Absolution failed to meet the studio expectations.

With the new Hitman trilogy releasing under a "games as a service" model, the developers were able to update it with new targets, goals, and brand new rewards with the Elusive targets. In addition, the games have seen new DLC missions like Patient Zero which were significant to the narrative. Players are even able to add their own Elusive targets, creating their own levels and challenges to the game and ensuring it always feels fresh.

16 The Outer Worlds 
The Outer Worlds resembles a mixture of Bioware's Mass Effect franchise and Bethesda's Fallout series, in terms of both story and gameplay. Like those games, Outer Worlds also got DLC: Peril on Gorgon and Murder on Eridanos.

Peril on Gorgon adds new perks, flaws, NPCs, items, quests, as well as an entirely new planet to explore. The level cap also got an increase, allowing players to build even stronger characters. Murder on Eridanos is a much more narrative DLC, appealing to players who love good storytelling. It also adds to the level cap and introduces new flaws and perks, new characters, and more items.

15 Diablo 2 
While Diablo II may be over 20 years old at this point, it is still relevant to modern gamers. After all, the game's remaster is set to be released this very year, with the DLC integrated with it buy Diablo 4 Items.
