British newspaper The Guardian (aka as the Grauniad because of its relaxed approach to proof-reading) ran a short piece about the possible resurgence of interactive fiction (aka gamebooks) on ebook readers.
I like the idea, but having written dozens of sword-n-sorcery gamebooks over the years, I'd be interested to try something new. Maybe an interactive thriller, a romcom or a historical novel?
I'd also chuck out the dice, percentages and stats. With paper-n-pencil gamebooks all that stuff was just there by historical accident, a hangover from D&D. In the case of e-gamebooks, the device could take care of all that so that the reader can concentrate on the story.
