Some lists don't have titles that are on other lists simply due to this, and some newer titles appear infrequently but with a lot of points due to their recency and quality.
The final issue is simply publication date. Some lists don't have titles that are on other lists simply due to this, and some newer titles appear infrequently but with a lot of points due to their recency and quality. They are lower on the overall list but have high average points. To combat this, we can sort by average points as well for fun, although that does lead us to see a random-ass game that somebody put at #1, making it the only game with a 100-point average.
