Random Key Dump

Was clearing out my google drive and I found a document with some keys in them. I have no clue how many have been used and some of them I don't know what game they're for. Regardless I'll dump everything here in the hope someone can get use out of these keys which have just been gathering dust.

I'd appreciate if you take a key, let me know so I can remove it.
