A trailer for the Playstation 2 port of Half-Life is up at 13th Street. GameSpot is reporting that Presto Studios, most recently known for Myst III: Exile is currently working on an original action game for the Xbox (as well as an Xbox port of Myst III). Also on GameSpot today are hands-on impressions of Unreal Championship, the original Xbox Unreal title from Digital Extremes. And finally, this European Game Boy Advance commercial really has to be seen to be believed.
