What do people want? Photorealistic graphics in a Monkey Island game? What's the point in that?? Oh yeah, and they probably want a dark and gritty Guybrush that has internal confilcts when he has to steal something from someone. I don't want "The Dark Brush", thank you.
But it's true that if people don't like something from the start, they won't continue or try it again. I guess that people on the internet are too busy doing other things...
I had a similar problem with the first chapter. I played it all the way through, I laughed, I enjoyed it, I was smiling from ear to ear while playing it, but for some reason I had no rush in playing the next chapter. But when Chapter 2 came, I got hooked. I know that a lot of people dislike this episode, but I love it. Of course, as it went along, it got better. And that's exactly what I loved about the concept of episodic games. I couldn't wait to see what happened next!
So imagine if ToMI would have been one single game, released in one date altogether. Would the twists have had the same effect? Would people connected with the characters as much as they did? Probably not, because the story only works with the episodic format. It's like a TV show: You can't wait to see the next episode and see what happens next.
Just my complicated two cents.
