1. Advance Wars: Black Hole Rising
2. Advance Wars
3. Final Fantasy VI
4. Final Fantasy Tactics Advance
5. Tactics Ogre: The Knight of Lodis
6. Golden Sun
7. Pokemon Sapphire
8. Mario Kart Super Circuit
9. Fire Emblem
10. Pokemon Leaf Green
Both Advance Wars games were for me the best games the GBA had by a huge margin
