It's very good to know that I can forgo 57 missions on Gold. Some of them are long, irritating missions I won't feel like retrying to get Gold on, while others (like some of the Rampages) are tough. I think the second or third Rampage had me scratching my head at how I got as many kills as possible while managing not to die, and I still needed 15 more for Gold.
