May the fourteenth be with you: Star Wars: Knights of the Old Republic
and Jedi Knight 2: Jedi Outcast
are each available on Mac and are 25 percent off on Steam today, in celebration of "May the 10 days after May the fourth be with you" day or something. Each title costs $7.50 with the sale, which ends May 21 at 10 a.m. PST.
Both games first dropped in 2003 but they hold up pretty well nine years on, especially at less than $10 -- at least they've aged better than we imagine The Old Republic
will have by 2020.
