This isn't about Valve either. Because you know, games are busy.
Kieron posted a couple of days ago about the freshly confirmed release date for Puzzle Quest: Challenge of the Warlords, on the 22nd Oct. Turns out their "confirmation" wasn't enormously accurate, what with the game being on Gamersgate today.
It's a teeny weeny download of only 85.8MB (exactly six Peggles) (don't believe the 58.94MB (4.12P) lie on the game's main page), but you do have to jump through the fiery hoops of Gamersgate's registration, then paying, then downloading their downloader, then downloading the game proper, then installing it. Which doesn't take long, but blimey.
But hooray! This year's Trinity of Puzzle Games is complete.
