Games should only be realistic to the point where it is "fun".
A simple example, a friend of mine is a game designer and he designed the AI for an enemy helicopter in a game. He spent days reading the helicopter's specs for lift, manoeverability, weapons specifications like rate of fire, etc. The he modelled the helicopter's behaviour faithfully on these parameters.
... the end result was a completely unbeatable opponent (but who's really surprised, I mean computer games and movies are full of lone gunmen taking out attack helicopters, but in reality unless there are very specific conditions that just doesn't happen).
Finally he lobotomised the AI and specs so it was beatable, because it simply wasn't fun to play against an unbeatable opponent where the only winning strategy was to either drop your pants and bend over for a hot lead enema or run like a mad ferret from cover to cover and just PRAY you got through on the 20th or 30th attempt.
So yeah, you cut out the realism when it ceases to be fun. For a game like Sam and Max that means that realism never even gets a nod. For most so-called "realistic" first person shooters that means there's maybe about 20% realism, because honestly real combat isn't about skill, it's mostly luck like whether you step on that IED when you step off the path to take a dump or whether your friend does. Real combat isn't the stuff of computer games, because it's huge stretches of boredom followed by sudden and unexpected heart-pounding terror.
