Note about the "Opal O'Donnell" pseudonym
For a while, Adam Cadre claimed that "Opal O'Donnell" had assisted him by entering his game Photopia into IF Comp 1998 under her name and e-mail address. Supposedly, Adam had already talked to Opal about borrowing a game element from her ChickenComp game (which she agreed to), and by letting him enter the competition under her name as a pseudonym, he was able to avoid comparisons with his earlier game I-0.
But, more recently, Adam revealed that there never was an Opal O'Donnell: it was just a pseudonym. See the Photopia Phaq for full details.
