User blog comment:Drink800/ I have an actual GAME DISC of the Dreamcast HALF-LIFE that plays on ANY Dreamcast!!/@comment-76.75.94.191-20140727024353

I made this disc, sometime in 2006 IIRC. I made and sold about 20 of them, along with some Propeller Arena and Ikaruga discs. Flame away, but I sold them cheap, and back then many people did not have the knowledge or ability to burn DC games themselves, taking into account what I paid for the discs and the paper for the inlay, not to mention my time making the things, I probably netted about $7 a disc. I made it very clear on my listing that people were getting a homemade product, these discs were never sold as being an original Valve-made item. Eventually eBay made me stop listing them. FWIW as early as 2004 I was seeding a copy of the Half Life Gold image on two (now defunct) scene sites. I came into possession of the image after many, many hours of trawling some of the murkier parts of the internet.

So what you have is rare I guess, I've never seen another mentioned by anyone on any of the sites I frequent, the gamegenius branding was mine, and was my eBay username at that time. Is it valuable? No more than any blank CD-R, sorry.

BTW I forget the brand of discs I used, I bought them from a local independent computer store, I liked the prototypey look of them.
