Diablo 4 tried to repackage Diablo 2's grind for the modern era, but series overseer Rod Fergusson says the "consumptive nature of a live service" made it unfeasible
A game that does seasons very well is Deep Rock Galactic. Each season comes with fresh new content. Old seasons can be revisited if you missed them, so no stress. The new additions to the game are permanent, which adds great variety to the missions. Progress follows between seasons, so no need to create new characters from scratch.
Most importantly: the game is really good as well.
For me the first two-the weeks are the best anyway. Everyone starts fresh, the economy is fresh, activity is happening.
Gives the game new life
Diablo bores me, but with PoE it's very exciting. And with every league you pay you become better at the game, so the next league you know more and you'll make stronger characters and farm better items
