Shortly after Half-Life: Blue Shift, the standalone Barney episode originally planned for inclusion in the Dreamcast port of Half-Life (story), reached store shelves, Sierra On-Line announces that this Dreamcast port is now cancelled altogether. Here is the brief statement we received:

Sierra regrets the cancellation of Half-Life for the Dreamcast due to changing market conditions.

And in related news, there is a quick Q&A with Randy Pitchford on Hangar 16, in which the Gearbox Software lead designer reflects on the just-released PC version of Blue Shift (thanks GameSpyDaily).
