The PC version of GTA V has been delayed until March 24th, but Rockstar's trying to ease your pain by offering a pre-order deal. You will get not only $500,000 in game for both GTA V and GTA Online, but also a free game of your choice from a list that includes other GTA games, Max Payne 3, LA Noire, and more.
There are tons of reasons why you shouldn't pre-order games, but if you do, check the deal out here.
