Rating systems from magazines use only the final percentage score given by a publication, even if the magazine ranks individual components of a game such as music or graphics.
A-F ranking systems
In order to calculate reviews which use A-F rankings, we have adopted a numerical conversion chart keeping in line with those used on aggregate sites such as Metacritic and Mobygames. This allows for simple calculation of a game's review on a 100-point scale.
| Letter | Value |
|---|---|
| A or A+ | 100 |
| A- | 91 |
| B+ | 83 |
| B | 75 |
| B- | 67 |
| C+ | 58 |
| C | 50 |
| C- | 42 |
| D+ | 33 |
| D | 25 |
| D- | 16 |
| F+ | 8 |
| F or F- | 0 |
Electronic Gaming Monthly
Reception scores for Electronic Gaming Monthly are calculated by taking the average of the three or four (depending on the era) review scores given by each reviewer and determining the mean average. From there, the decimal is carried from a 10 point system to a 100 point system. After April 2008, review scores switched to an A-F ranking system and should be calculated by the previously mentioned chart, and again, the mean average should be derived for the final score.
- Example 1: In the July 1991 issue of EGM, 688 Attack Sub receives scores of 5, 6, 6 and 4. The mean average for these numbers is 5.25. This is carried to a 100-point system and made to 53.
- Example 2: In the December 2007 issue of EGM, Sega Rally Revo receives scores of 7.5 from Gord, 7.0 from John and 7.0 from Greg S. These three scores give a mean average of 7.1667. This is rounded to 7.2, then carried to a 100-point system of 72, resulting in the final score given by the magazine for that game listed on the page.
- Example 3: In the April 2008 issue of EGM, Sega Superstars Tennis receives scores of B- from Andrew P., C+ from Ray, and C from Joe. These scores are translated to 67, 58, and 50, and then averaged to become 58, the score for the magazine listed on that page.
Mega Play
Reception scores for Electronic Gaming Monthly are calculated by taking the average of the four review scores given by each reviewer and determining the mean average. From there, the decimal is carried from a 10 point system to a 100 point system.
- Example: In the August 1992 issue of Mega Play, Kid Chameleon receives scores of 7, 7, 8 and 8. The mean average of these numbers is 7.5, which is then converted to 75.
