Valve’s Steam digital download service is having their annual Christmas sale through Sunday and there are amazing deals every day. If you check it each day, you could walk away with some seriously AAA games for less than $5 each. Today, however, has Need for Speed: Hot Pursuit on sale for 40% off, which puts it at a cool $29. We let you know how it’s the best racing game of 2010, and for $30 it’s impossible to pass up. The PC version is the best of the three, if you have the system to run it. You’ll need to hurry as this deal is only good for 24 hours and expires at 10:00am Pacific tomorrow.
