Would this have been feasible? A full gamebook adventure in a 64-page graphic novel, say? Looking at it now, it would have been a fair old bit of work. But hard work wasn't something either Russ or I would shirk from in those days.
One thing I'm glad to say is that my dialogue writing skills have improved a little bit since then! Anyway, nothing we were contemplating in '87 approaches the mind-bending complexity of Jason Shiga's brilliant branching graphic novel Meanwhile, which is well worth a look to see what happened when gamebooks grew up.
