It looks like Casey Hudson, director of the original Mass Effect trilogy, is a huge fan of Top Gun. Further, he worked a reference to the 80s classic into the opening text of the first Mass Effect game, which has apparently gone unnoticed until now. In fact, the opening text is the reference.
As pointed out by Twitter user MissSnizabelle, when seen side by side, the similarities between the two texts are clear. The layout of the script, and the way the title is introduced, it's so obvious! Top Gun itself was released in 1986, and Mass Effect launched in 2007, meaning this one has been right there, out in the open, for some 16-odd years.
What do you think of this Top Gun reference in Mass Effect, hiding in plain sight? Pretend you thought this was common knowledge already in the comments section below.
