Easy. Dungeons And Dragons.
Hear me out:
1. It can literally never get boring because it's powered by your imagination.
2. If you don't have a local group, you can play online.
3. If you can't find a group online, solo play books exist.
4. You can use this as the ultimate open world sandbox game and just have fun.
Yeah you're just playing pretend with some dice, but answer me this: When's the last time you played a game in which you took magically powered mech suits to the core of the sun to box a solar dragon? NEVER, that's when!
Heroes need foes to test them. Not all teachers can afford to be kind, and some lessons must be harsh.
