We will be using the bfi data (bfi is a data frame available in R), which has 28 variables, and 1000 observations. The data are the results of a study of 1000 individuals who were asked to rate themselves on a Likert scale of 1 to 6. The last three variables in the data frame report age, education and gender.

Question 2: Draw a diagram with factor analysis loadings based on the results of question 1 (only show the biggest loading per item). Read the table above, understand the meaning of each item, and try to name one of the factors/components extracted in question 1.

M: I'm not wasting the holidays as you say. The computer is a good thing. On the Internet you can go to any part of the world; I can see everything in the world. It's more real than reality.

W: But... but you can't spend your entire summer watching that screen. You'll get a big bottom.

M: I'm not just watching the screen. I'm doing a lot of things—I'm sending e-mails, I'm learning things, I'm chatting in chat rooms...

W: Right! But I'll bet you're spending most of your time playing computer games—a time-wasting, mindless activity that'll turn your brain into Chinese doufoo.

M: No, it isn't a single mindless pastime. It's many activities: role-playing games, arcade games, adventure games, strategy games...

W: I understand the computer is a wonderful thing, but you have to be careful not to get too much of a good thing. Every life needs some variety in it. It would be a lot healthier if you played a chess game outdoors, in the park.

M: It wouldn't be the same. In those games in the park I can't play against the grandmaster of Moscow, can I？ And there are creative games in the computer, where I can learn city planning and psychology.

W: Well, what about me？ Don't you think I'd like a little attention？

M: Now, Baby, that's no way to talk. After all this time together, you know I love you.

W: I'm not so sure any more. It's time you made a choice. Is it going to be me or the computer？

M: Well...

The new series of “_Minecraft: Story Mode_” will be set in the world of _Minecraft__,_ but it will feature an original story that combines new characters with familiar themes. It is driven by player choice. It will be a separate standalone product.

The decision to make the new game community-driven is potentially brilliant. It’s interesting that feedback from the community is going to be brought into _Minecraft: Story Mode_. In a way, it echoes what _Minecraft_ is. It is a user-generated world.

It’s likely that there already have been gamers on _Minecraft_ fan blogs. They have come up with theories as to how the universe was created. There could be lots of contradictory things there. But from a marketing standpoint, it makes all the sense in the world for the community of “you guys are going to write this.”

_Minecraft_ first came out in 2009 and is probably due for an evolution of some sort. _Story Mode_ seems like a natural next step. A dedicated fan base has very high expectations. It will be satisfied with the story it is developing.

There will be challenges, however. _Minecraft_ does not follow what the game industry is used to working with. It will be a completely different development scenario. It is a world with no story and starting from the beginning. As long as the _Minecraft_ story is popular and successful, that might be OK.
