Follow ups or expansions of some of the best things that have come out the last 100 - part retrospective, part new things to use in conjunction with prior content!
Great idea.
Or a challenge of how to take a prior adventure or patron or something and rejig it for the 100th - another flavour that preserves some aspects, but sets others on their head.
Oooh, yes.
In preparation for my final suggestion, I have retreated to my deep meson gun bunker.... you could just double the page count for issue 100! <ducks, runs, hides>
I was going to suggest that. It's what I did for the 500th issue of the thing I edited for ten years. Only I decided there wasn't a bunker deep enough...
:-)
(Plus, I figured, we're already on double sized issues!)
I really would have to change how I bind my print out in that case though. My 'let's just fold and staple them' approach only *just barely* works for 60-70 pages. Which is, what, 15-17 sheets of A3.
But yes... double sized would be another 'tradition'.
