- A game only enters the ranking with at least 80 external ratings, so a single enthusiastic review never outranks a proven classic.
- Community grades from F to S are shown next to every game, and only stated as a fact above 5 Tier ratings.
- Release window covered: 1970 to 2026.
- 7 games are listed on this page, carrying 5,521 ratings between them.
