Lucasarts announced last night that the Jedi Knight series of Star Wars shooters will be making their way to Steam next week.
Which is a slightly confusing statement. After all, Lucasarts' FPS Star Wars titles began in 1995 with Dark Forces, whose sequel, Jedi Knight, was Dark Forces II. Making it part of the Dark Forces series, not the Jedi Knight series, the name the games assumed when moving onto the later Jedi Outcast and Jedi Academy.
So I guess what we're trying to say is: we really hope Dark Forces is included, because it probably did the best job of the lot in really nailing the tone and "feel" of Star Wars.
UPDATE - Yup, it includes not just Dark Forces, but Jedi Knight's Mysteries of the Sith expansion as well.
