Depends what youre into?

World of Tanks and World of Warships have daily missions and quite some grind behind them, as well as War Thunder. But all of them are PvP Games that require Internet

Pretty much all MMORPGs have dailies, the following are the "most active" ones as far s I regard:

Elder Scrolls Online

Fallout 76

Final Fantasy XIV

"Wynncraft" if you already own Minecraft and want something extremely casual

Otherwise as a exploration/sandbox "No Mans Sky" also has some dailies in the Anomaly, as well as you can tact in the grind for upgraded spaceships, weapons, vehicles and such.

What about Rogue Lites without dailies, but lots of Unlocks? Like Risk of Rain (2), Binding of Isaac, FTL Faster than Light, Gunfire Reborn, Enter the Gungeon and so many more?

Titanfall 2 also exists, with a short but great Campaign and an Onlinemode with the usual CoD-esque Unlocks for Weapons and your Titan. It has a PvP and PvE Gamemode
