Re: Any news about "Storming the Wizard's Tower"?
So, to answer my own questions: In a recent episode of "The Walking Eye"
there is an interview with Vincent Baker. It is mostly about Apocalypse World
but towards the end he also talks about some other projects. Regarding "Storming the Wizard's Tower" he said (if I understood everything correctly) that it has some mechanical problems and that he is still trying to figure out what to keep and what to change.
So, I guess we'll have to wait and see...
Having just listened to that episode also, I can confirm your interpretation - he mentions it has design issues he's still trying to resolve.
