8. Buzz Aldrin Has A Voice Cameo At The End Of Mass Effect 3
BioWareNow, here's something to make your day. Mass Effect 3's climax may be regarded as a crushing disappointment to most players, but there's one thing it got right: the casting of the second person to ever walk on the moon, Buzz Aldrin, in a small but significant role at the game's finale. If players opt to have the game end with the Crucible being activated, we see an elderly male (called the Stargazer) telling the tale of "The Shepard" to a young boy, suggesting that despite a clear passage of time, Shepard's legacy has endured. It's not an immediately obvious cameo to anyone but the most devoted NASA nut, but considering Aldrin's immortal status in the realm of science and space, it's a fitting role, and one that Aldrin delivers beautifully despite the ending's other misgivings.
