I downloaded an ISO of it a while ago and played through maybe third of the game. I found it to be very playable. People always mention the long load times, but it's worth mentioning that long load times were much more common back then. (Although Half-Life on DC was even longer than usual.)

Also, I hate to be nit picky, but the blog post linked here manages to be weirdly wrong about two things and it's barely one paragraph long, lol.

Half-Life is one of the most successful video games of the early 2000s.

Ahhh, 1998. One of the best years of the early 2000s.

Half-Life was everywhere... except one notable place: Sega's Dreamcast. It has been a mystery as to what happened with a game destined to have a port on every possible platform.

Half-Life was a PC exclusive until the PS2 port in November 2001, ten months after the Dreamcast was discontinued. The PC and PS2 versions are still the only official versions to this day. Half-Life is not known for being on every platform. Was the author thinking of Doom, one of the best games of the mid 70s?

Semi-related, but to this day I remain impressed they got Half Life 2 ported to the original Xbox.

The prototype is out there if anyone with a Dreamcast wants to check it out.

I swear I downloaded and played Half Life for the DC back when I had the machine. I think it was Blue Shift which was originally going to be on the DC first (as an exclusive?).

It was perfectly fine to play but I guess due to hardware limitations, the areas in which you played weren't that large and loading times off the CD was quite slow.

8D hehehehe so much goodness
