Maybe Valve will add insult to injury and announce Artifact 2 as their next game.
Anyway, it seems they are completely incapable of doing anything worthwhile with Half-Life anymore.
No worries, life goes on, we don't need Half-Life this day and age.
But if you ask me - having one of the most beloved game franchises, having loyal customers for years on end, being constantly requested to do some more - only to turn around and no thing? Saying it's a great pity would be a huge understatement.
