How this ranking is built
- Games are ranked on the aggregated critic score out of 100 imported from IGDB and Metacritic, never on Tier's own grades.
- 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: 2018.
- 26 games are listed on this page, carrying 16,163 ratings between them.
- Rankings are recomputed hourly; this one was last rebuilt on 28 September 2026.
