The first thing you can say about Never Settled Forever (NSF) is that lawyers were involved with its creation because forever is defined as infinite time up until December 31, 2013 when the program ends. With that downer in mind there is a lot of good in NSF including three tiers called Bronze, Silver, and Gold. With these levels you can pick one, two, or three games from a list depending on which card you bought.
It works like this, buy a 7700 series card and get a Bronze bundle, 7800 series for Silver, and 7900 for Gold. You either get a physical card in the box with a code or an email with that code in it depending on who you buy the card from and what brand it is. In the end you get the same bundle regardless of the delivery method.
