Trivia: While Guy fights with Dude, there is kid with a red shirt watching the game. Behind his back there is a Deadpool poster, another Ryan Reynolds movie.
Trivia: Ryan Reynolds wanted Chris Evans to have a brief cameo in the film. Evans was incredibly busy working on another project, and told the crew that while he definitely wanted to do the cameo... he literally had to be in-and-out of set in about ten minutes time because his schedule was so tightly packed. The crew did everything to prepare for Evans arrival, and once Evans got out of wardrobe/makeup and onto set, they were able to get his scene filmed and get him out in only seven minutes.
Trivia: In one scene, a power-up is just barely visible in the background. It's a bottle marked "Subtle Product Placement." If you look very closely, you can actually see that it's a bottle of Aviation American Gin. Star Ryan Reynolds partially owns a stake in that brand of gin, and has made numerous humorous videos online promoting it.
Trivia: In order to help promote the film, Ryan Reynolds and Taika Waititi filmed themselves reacting to the trailer in character as Deadpool and Korg from the Marvel Cinematic Universe, respectively.
Suggested correction: As one of the principal developers of the simulation engine, Millie recognizes that Guy is a non-player character (NPC) who merely obeys a loop of coded actions, and he's supposedly incapable of acting outside of his code. So, she means that NPCs can't just arbitrarily kiss players. Players can do whatever they want, but NPCs are mindless robots. At that point, however, she doesn't realise that Guy's Artificial Intelligence has evolved to independent self-awareness, allowing him to act outside of his code.

Key's actually says "There isn't a button for that" when Millie brings it up. There would be no way for her to initiate, as her in game actions would be limited to the controls offered.
By the time Millie kisses Guy, we know that the Free City simulation engine was already undergoing Artificial Intelligence evolution, essentially rewriting its own code, allowing Guy (and other NPCs) to achieve independent self-awareness. It follows that Free City was probably rewriting its player code, as well, making all sorts of new and startling functions possible for players and NPCs alike.
