You’re right if you’re looking at it as the final picture after everything has been released. But one of the things people talked about a lot on Qt3 and on various gaming podcasts was that during those episodic releases, when only Paris had been released, people played Paris over and over, and really got to trying different ways to accomplish the objectives within the same sandbox. A lot of people said that they never would have done that normally, but with the episodic release, it really enabled them to try different approaches to the same levels while they were waiting for the next release.
I didn’t play the game myself, but I know exactly where they’re coming from. If I have the whole game available at once, then I’m going to finish Paris and move on to the next level, I’m not going to play Paris again to try it in a different way.
