I was just scrolling through my most played on Steam and the closest one to average that I can think of is probably . It’s basically a space colony building simulator. This is the kind of game that you boot up once every 3-4 years, play through a whole colony, and then uninstall and forget about. Not bad by any means, but I wouldn’t say it’s very exceptional either. While it has some challenge scenarios and different planets with their own characteristics, the game boils down to the exact same formula once you get a self-sufficient base started, and therefore replayability is really not there. However, it has entertained me for over 100 hours in the past 8 years, so do with that information what you will.
A perfect 5 or 6 out of 10.
The issue here really is medium bias. Different mediums of entertainment have different “average” scores. It seems (i think) like things that take more time to enjoy (video games, TV) have higher baseline scores that are considered average than say a movie.
In my opinion and not based on fact, i think that school grades also impact that bias a little bit (59 or below (some 69 or below) is a failing grade). This might provide some additional basis for 50% being a below average score, in spite of it being mathematically accurate (unless the scale is 1-10).
All that being said, i don’t think most would agree that a 5/10 is average. I would be willing to bet that average for a video game would fall into the 7-7.5 range for most people. There are probably other biases at play as well, many of which i believe are impacting the scores in the first place. If i saw a game with aggregate reviews of 7.5, i would think it had major problems and may not be worth my time investment. 7.5 is almost certainly not a “high” score.
