A Tale of Swords and Souls, Retold.
I spent a lot of time playing SoulCalibur II on the GameCube during that era. It looked pretty, played well, and featured guest characters that were appealing – especially Link. SoulCalibur II HD Online pays a nice homage to its original port, and it stands up quite well. The fighting remains tight, and the game remains visually pleasing. Unfortunately, the slim online offering makes this one a tough sell especially if you still own the original.
