I would call "Out of the park Baseball" an outlier, it only has 5 reviews and they are not all from what you'd call good sites. I would strike it from the list if I was you.
In addition to this I would say that Falcon 4 was an outlier as well with only 7 reviews posted. The trend is generally downward and its not fair to compare games with 60 reviews to a game which has merely got 7.
Lastly, this is optional but I would consider the generation as starting in 2006 because the Xbox 360 was only released near the very tail of 2005.
Tease.
