Shadowlands looks promising!
I know a lot of us are on the Classic WoW ride atm, but the next expansion for WoW looks very promising. The Tower for example, we will get to test this tech in the next patch for WoW Live.. the scaling by group members part. The changes to leveling sound great as well. When you complete the story on your main, your Alts can pick and covenant and do world quest right away! Alts will also be able ( and new players ) will be able to level 10-50 in ANY expansion zone! that sounds amazing! ( off topic but Diablo4 sounds great as well )
Torghast, Tower of the Damned
Within the Maw is a towering structure known as the Tower of the Damned. To uncover the secrets of the Jailer, players will need to venture into the tower. Inside, players will find an endless and ever-changing dungeon; you’ll be able to explore the labyrinthine halls either solo or with up to four friends, and the experience will scale based on the size of your party.
