Games for Windows Live Adds ‘Games on Demand’ Downloads

I feel bad for Microsoft's Games for Windows, a really great idea that for one reason or another has yet to blossom. I've previously grumped about it here and here, so I'll summarize: Launched in May 2007 with the Windows version of Halo 2, just 29 official LIVE-enabled titles since, and dozens more GFW-branded games that have Xbox 360 analogues, but no corresponding Games for Windows LIVE support, thus: No GFW-based matchmaking, achievements, and gamertag tracking.
