I may have been a little premature based on my Beta experience on dismissing the puzzle/investigation mechanics of TSW. The problem being that I was getting bored of the general gameplay before I actually got into any of them. But, it was one of the features that I was most excited about when I initially started following the game, so it kind of put me off of the game when I was immediately going into the well-worn kill X quest treadmill etc etc. But I'm not ready to entirely write it off yet, I suppose.
For the people playing, how much of the game does it usually comprise? Does it feel shoe-horned in? I thought the original meta game ("A Friend" email) to get the beta invite was really interesting, and it got me pretty excited with what they might do with it. I'm in the middle of catching up on the Bombcasts, and Jeff talking about it has me curious again. So there you have it.
