While "Other Games" is fine for the myriad of independent games and lesser known rule systems, I think "Playtesting" should be a selectable option. First it would let people know that the rules are still in flux, which may make players that prefer faster paced games pass it up to avoid frustration. Second, (and this is why I'm recommending it), players who are also trying to develop their own systems can find each other and compare notes and ideas. This way instead of just listing all "Other Games" we can zero in on other designers and writers in order to help each other build our ideas up.
