The original Xbox was a groundbreaking console, showcasing impressive graphics and performance compared to its contemporaries, the PlayStation 2 and GameCube. Its library included iconic titles like the Halo series and PC-inspired games such as Star Wars: Knights of the Old Republic and The Elder Scrolls III: Morrowind. Despite the lack of backward compatibility for many titles, passionate gamers can now revisit these classics via their Steam Deck with the help of EmuDeck.
