I was going to say replaying but I feel like that limits the question to games like Prey or Fallout New Vegas that have endings and games like The Sims 2 or Cities Skylines where you can play indefinitely end up excluded.
I’m not really referring to games like League of Legends where you’re coming back every month. More so games where you stop playing for an extended period of time.
Mirror’s Edge, Jet set radio future (and now bomb rush cyberfunk)
The 3D Mario’s (I haven’t gotten around to playing galaxy 2 yet and it’s eating me up inside lol)
Skyrim, Minecraft, stardew Valley
Ocarina of time and majoras mask.
Animal crossing (usually whatever latest entry, but I liked new leaf the best so far)
Lumines has become an addiction
Forza Horizon (similar to animal crossing, usually the latest entry, but surprisingly I enjoyed 1 and 4 the most. I was surprised about 4 because I didn’t think I really cared too much about the location, but I liked the seasons a lot. It kept everything feeling new)
Kirby and the crystal shards
