The OHRRPGCE Top 30 was a vote by the community for their favorite OHR games held (usually) twice a year from 2000 to 2009. The more recent ones are archived here:
The original Top 30 lists were included with every release of first OHR Monthly and then Reasonably Septaweekly, and may now be found in the archives of Reasonably Septaweekly. However, the results of a number of Top 30 polls conducted between then and Summer 2007 have been lost for all time.
A good place to find well-rated OHRRPGCE games is on the Slime Salad Gamelist (sorted by rating)
