The 8 Modes of Interactivity (as far as I can see)
i) The Arcade model
Like Terminator: kill or be killed.
ii) The Coffee Table Book model
Enter anywhere/leave anywhere; pointless in the end;
zero replayability factor.
iii) The Universe Creation model
I built you and I can crush you.
iv) The Binary Tree model
Limited number of options; reads from left to right;
tightly controlled mini-dramas.
v) The Pick-a-Path model
Does our hero smooch with Heather Locklear, or
not--you decide! Expensive. Unproven entertainment value.
Audiences don't pay money to work.
vi) RPGs (Role Playing Games)
For adolescents: half-formed personalities roaming (in packs)
in search of identity.
vii) The Agatha Christie model
A puzzle to be solved using levels, clues, chases, and exploration.
