List of 1000 games on sale
Attached text file has list of 1000 Steam games on sale sorted by savings
Sorry I couldn't provide the full list of 1300 games but the rss reader I used limits the feed to 1000. Thank you to SteamGameSales.com for the RSS feed.
For those of you interested in the method I used, I've attached a small piece of the rss xml file I downloaded. Using Cygwin (bash shell port for Windows), I wrote the following command to strip out all the junk in the rss file and copy the contents to a new steamGames text file.
cat rss.txt | grep title | cut -d ">" -f2 | cut -d "<" -f1 | sort -r > steamGames.txt
