I am creating a game that has a great deal of items in the game. For these items I wanted to add some "educational" pop-up text when players hover over a certain item in the game. My idea was to simply take text from websites like Wikipedia (I understand the "reliability' issue already) and put them in as extra "flavor text" in my game like in the picture below (The text is in the while box at the bottom of the tool tip):
Most of the content in Wikipedia that I want to do this with is under the "Creative Commons Attribution-ShareAlike License" (CC-BY-SA) and this is where I get very confused.
I have been doing some very exhaustive research on this. And to try to put this as simply as possible. Even though the content on Wikipedia can be freely distributed. Apparently under the CC-BY-SA license, it is argued that wherever the content is used with that license, ALL MEDIA attached to that content is now also under the CC-BY-SA license.
So from what I read, it may be inferred that my entire game, images, artwork, source code, and everything else, is now under CC-BY-SA license, and I must make my entire game publicly available for free because I have added this one line of text.
So my question is: Is this true? Should I just do my own independent research on the each subject and put all of the descriptions in my own words?
Also I plan to sell this game commercially, so I do not wish to make my game freely available obviously. Also I plan to have hundreds, even thousands of objects in the game, and doing research for each one is a great deal more time to come up with a paragraph or two for each object. I am just trying to see if I can avoid that, as my time doing actual game development is much more beneficial.
I have no problem giving the citation credits for each passage as in the image. But is this CC-BY-SA licence going to make it so I cannot give anyone credit at all, and I just do my own research?
