What other True20 material would work well, or seamlessly even, with Interface Zero? Apart from the core book, of course.
Even better, have you (or anyone else reading this) found that there are particular books or PDFs that
do work seamlessly (or really well) with IZ? I know, it hasn't been out long, but thought I'd ask anyhow.
Also, which areas that Interface Zero doesn't cover (yet?), might be covered by future supplements? So, implied in that: What's the breadth and depth of IZ, as it stands?
