Aspyr Media are working on a full remake of Star Wars: Knights of the Old Republic, arguably the greatest and best-regarded Star Wars video game of all time*.
Knights of the Old Republic, developed by BioWare in association with LucasArts, was released in 2003. Set roughly 4,000 years before the events of The Phantom Menace, the game tells the story of a war being fought between the Galactic Republic and its Jedi defenders against a Sith army and fleet led by Darth Malak. The player takes on the role of a character of their own creation who is roped into helping rescue a Jedi Knight named Bastila Shan from the city-planet Taris. As the game continues, the player acquires a large array of allies, such as the murderous and meme-generating assassin droid HK-47, and learns a shocking secret about themselves. Events culminate in a final battle between the Republic and the Sith Empire.
The game was immensely successful on release, generating both critical acclaim and high sales. It was followed by two sequels: the more ambitious but more divisive sequel, Knights of the Old Republic II: The Sith Lords (2004) from Obsidian Entertainment; and MMORPG The Old Republic (2011) by BioWare themselves. Although set in an original universe, the later Mass Effect trilogy (2007-12) draws on some structural ideas from Knights of the Old Republic.
It is unclear how thorough a remake this will be, since no gameplay footage has been shown. The "remake" title and the age of the game and engine suggest that it'd have to be a much more thorough reworking of the game from scratch, possibly in a new engine, rather than the "retexture-and-polish" style of remakes like the Mass Effect Legendary Edition.
Knights of the Old Republic Remake is "early" in development and no release date has yet been set. So far, it has only been announced for PlayStation 5.
* Arguments for TIE Fighter, Republic Commando and Jedi Outcast can be heard at a later date.
