HomeLAN Fed has a nice Q&A with Jim Tso of LucasArts about Indiana Jones And The Emperor's Tomb. I'll just copy this text straight from Shacknews as it saves precious time:
Q&As are about picking The Collective (Deep Space Nine, Buffy for the Xbox) as developer, why the game is coming out on multiple platforms, the settings in the game, how combat will be handled and why this game will be more action than adventure, among other things.
HomeLAN - What was the genesis behind the actual storyline for the game?Indiana Jones And The Emperor's Tomb will be released some time next year... maybe.
Jim Tso - We wanted to take Indy someplace that hadn't been explored in previous movies or games. The Far East seemed like a natural choice. From there, it was easy to pick 1930's China as the location since it offered so many opportunities for gameplay and storytelling.
