Here's why:
* Ace Assault focuses on specific ships. The game features a specific set of starships for players to pilot, and Mace Windu's Jedi Starfighter is not included.
* Different game focus. Ace Assault is designed around dogfights and aerial combat, while Mace Windu's Jedi Starfighter is primarily associated with ground combat and lightsaber duels.
* Game release date. Ace Assault was released in 2005, before Mace Windu's Jedi Starfighter was introduced in the Lego Star Wars video game series.
