The definition of a "real game" gets extremely relaxed in a competitive situation between low-rated players. Between two grandmasters, they're going to stop the moment the outcome becomes clear. But when you have two just-above-beginners, there are other factors. They're going to keep playing in lost positions where there's a big material imbalance. They're going to miss a lot of mates in 3+ moves, and even simpler mates under time pressure. They end up in weird and "unrealistic" positions that aren't even interesting as puzzles, but have competitive significance to them because if the player with a big positional or material advantage loses on time or makes a blunder under time pressure, it will affect their rating and their standing in a tournament.
