The same guy who conducted those successive, episode-specific interviews with Dominic Armato as Tales of Monkey Island was released is back with a new interview with Steve Purcell at Alternative Magazine Online. Although he's been asked them all before, the questions are good and cover Purcell's whole career. A little taste:
How did you feel about episodic gaming initially?
I always thought it would be a good fit. Even back at LEC, Ron Gilbert talked about wanting to do mini-adventures that you would pick up at the counter of the game store as you were checking out. Ron, Dave Grossman and I brainstormed some ideas for a Sam & Max episodic series. I think smaller adventures are easier to get your head around both in making them and playing them.
For more, the most constructive course of action would be to read the rest of the interview.
