What do you see as the differences between writing cut-scenes and animation?

An animation script, like any full length story script, has to tell the entire tale. The cut scenes are just that - bits of cinema that move the story forward to get to the next bit of ass-kicking.

Doing game script stuff is more difficult because we were determined to tell an entire, solid story in the game.

If you did an Angel game, what sort of style would you use?

It would certainly have a different feel, a very different atmosphere, and I think different kinds of puzzles. But I think that, in general, the structure would be similar.
