Although Lost Ark is another clone of Diablo, it is extremely well done. It has been in development for the last two years and is set to be released early-to-mid 2017. The game is now only available in South Korea, and if the closed beta is successful there, it will be opened to the rest of the world.
The most interesting thing about Lost Ark is that all areas within the open world of the game are fully available from the get go. However, some of the areas can be restricted if you take specific quests to accomplish.
Lost Ark has a strong PvP component with several types of arenas for both small and massive battles between the in-game guilds. Another cool thing is the possibility to play card games in the taverns, which is truly a great addition to any modern RPG game.
