Very nice thread here Garcian Smith!
This thread is giving off some great PC love especially with ameratsu's Aquaria avatar (love that game and glad to see other spreading the word!)
The only thing I didn't see specifically mentioned were MODS which are one of PC gaming's biggest strengths imo. Check this thread for some new ones - http://www.vgchartz.com/forum/thread.php?id=96390
Also moddb.com is a great site that lets you track your favorite mods for updates and downloads.
Finally I started a modding social club, where we play old and new online mods that don't always have large user bases.
Feel free to join and have fun :)
