Pre-purchases are now underway on Steam for F1 2013, where Codemasters' Formula One racing sequel can be had for 10% off prior to its planned release on October 4th. In addition to the discount, this involves one of those escalating reward systems based on the number of preorders they rack up. They are already close to hitting the first milestone that adds a free copy of F1 RACE STARS to the deal, and the following two tiers will potentially add a 50% off coupon for any Codemasters game on Steam (except F1 2013 Mr. Sneakypants... you're the type who would try to wish for more wishes from the genie) and a free copy F1 2012. Here's a bit on the new game:
