Polyhedron on Archive.com

Several issues of Polyhedron magazine — either the RPGA publication or part of Dungeon magazine, depending upon the era — have been placed on archive.org for download or streaming.

Check it out if that sounds to be up your alley.

(For the record, I totally just downloaded issue #152 because it has the d20 Modern preview featuring the rules for the Thunderball Rally mini-game.  Especially since I already had issue #153 featuring both the orangutan race for Thunderball Rally and the Omega World mini-game.)
