My hope would be best techniques. Since it's more interesting when there's way more than 24 options to choose from. Are there even 24 arcs to really choose from?
1. Find the Dragon Balls/Emperor Pilaf
2. Training with Roshi/First Tenkaichi Budokai
3. Red Ribbon Army
4. Fortuneteller Baba (also part of above arc since both are about finding the Dragon Balls)
5. Second Tenkaichi Budokai
6. King Piccolo
7. Third Tenkaichi Budokai
8. Saiyans come to Earth
9. Namek
10. Freeza (people often separate the two)
11. Androids
12. Cell (again, people often separate the two)
13. Fourth Tenkaichi Budokai
14. Majin Buu
15. Evil Buu
Then there's filler arcs, GT, Super...
