i have a crossword android mobile game that is published on playstore. it's monetized by ads.
because this is a crossword game, i need a lot of words and it's definition. Currently it has 300+ level. I took most of the definition (about 95%+) from a dictionary (i have seek permission from them) and some are from Wikipedia.
Sometime the word definition from wikipedia is too long so i make it shorter, by cutting some word or replace it.
in credits section of the game, i provide the link to wikipedia.org. i cant provide link to each wikipedia page because there would be so many, and i don't remember all of them.
Will this be alright ? Is the definition in wikipedia count as fact or not?
I mean, i know Wikipedia won't sue me or something like that, and i don't live in US. But my OCD made my question a lot about license.
