[PC] Steam - Mad Max (89% Positive Reviews on Steam; Trading Cards) - $3.49US (~ $4.43 AUD) - Fanatical (Bundle Stars)

This is the all-time lowest price for this game (according to ITAD). The game is pretty good (as is reflected by the positive rating over almost 18000 reviews).
This deal last for about 48 hours from time of posting so if you want this game and want to play it fairly soon don't delay and get it. I assume it will be at least another year (if not more) until it drops significantly any further.
Note that if you but the game before the deal ends you also have a chance to win the Ripper DLC.
