PlayStation Network - The Darkness, GRAW2 demos and more

The PlayStation Store has some worthy PS3 downloads this week:

• Demos for The Darkness and Ghost Recon Advanced Warfighter 2
• Blast Factor: Advanced Research ($5), an add-on pack that requires the original $10 game
• Resident Evil 5 wallpaper (free)
• Movie Preview Videos: The Game Plan, Get Smart and Michael Clayton (free)

I'm going to keep downloading free demos and trailers until I fill the PS3 hard drive, even if I don't get around to playing them. I think I'm about halfway there...
