Some things that might be cool to include.
System reviews, especially newer or slightly less well-known ones (Mork Bork, Symbaroum, Forbidden Lands, Electric Bastionland, Seacat, Mothership,Troika, etc) . I think these are most useful if they’re no more than half a page.
System comparisons- any of the above, plus OSE, Lamentations, White Box, DCC (?)
Zinequest reviews: zinequest 2 zines are getting complete. Would be cool to get some reviews of these.
Creator Interviews Would be nice to have maybe one of this, a page longish, per issue. There are a lot of creators in here that would be cool to here from. I would love to hear, say, Jez Gordon tell us about Feral or Patrick Stuart tell us about updating a module.
Mechanics: This might be a little insider-basebally, but it would be cool to have like a roll over vs roll under article. Or some kind of depiction the range of 3d6 vs the swingy d20
House Rules: new ways to do initiative, experience levels, HP, etc.
