Who needs Christmas? November seems like a perfectly suitable time to send your savings account to Steam, which has Max Payne 3 for $3.99, Borderlands 2 for $7.49 and many more discounts as part of its autumn event. Likewise, you'll find tons of sales elsewhere, including Skyrim and Dishonored for less than $10 at Amazon, Battlefield 4 for $40 at GameStop, a Hitman bundle with Absolution for $9 at GMG and Far Cry 3: Blood Dragon for $7.49 at Get Games. Also, time is running low on the latest Humble Mobile Bundle, which offers nine games and various soundtracks for a few bucks.
