NxCmp: I see where you are coming from but you need to understand the argument. The whole purpose of a Let's Play is to add entertainment value. (IMO) You could watch it for fun, if you are bored or in a way how I see it. I enjoy watching others doing lets plays for games I have played because it gives me a new perspective. It's interesting to watch how others view the games you know or to see and try to understand how they choose to solve problems the way they did. It gives you a window to see how others may handle or tackle the game in a way you may not have. Understand ?
I do. A well written, fair point.
Personally I'd still rather be playing the game over watching someone else do it (in its entirety anyway) but I can see where you're coming from more clearly now. In one sense, you remove the required interactivity but still allow the user to follow the game. Making it more like a book or film. I can see how a game as well written as Arcanum could lend itself to that very successfully.
In another sense, my assumptions were correct about it being used as a walkthrough, following how somebody else has played the game, whether for problem solving, inspiration or just entertainment. All perfectly valid reasons and I'd guess a lot more intuitive than reading through a block of text.
I was just curious to find out if I was missing something, like a set goal of some kind. As the only full-game video run throughs I'd come across tended to be speed runs which focused on exploits or glitches to beat the game quickly.
