Time to break out the compressed air and blow the dust out of your video card’s exhaust slot. The annual Holiday Steam sale is here again, brining ridiculous deals on major releases, indie games, and entire studio catalogs. Typically each sale lasts about a day, with new stuff going up every day. The studio catalog sales tend to run through the duration, but it’s also possible that those go on deeper discount for one of those days.
Notable sales for the first day include the Witcher for $5 (but watch out for that 16:10 bug), Puzzle Quest 1 for $1.50, Bioshock 2 for $10 (you can earn Achievements on this one I believe), and Burnout Paradise for $5. Or just book the next 6 months of your life by grabbing the Bethesda Catalog, which includes Fallout 3, New Vegas, and Oblivion (and more) for $70.
UPDATE: It should also be noted that Xbox Live is also having a set of sales as well. Notable items of the day include Castle Crashers for 600 MS as well as a rotating list of daily deals (RDR: Undead Nightmare DLC currently 25% off).
