...they ARE all from games.
well...that's not entirely true.
For example there are Black Widow (MCU-version), Emma Frost (comics version), Raven (comics version), Griffith (Berserk anime/manga), Misato (Evangelion anime/manga) and Matoko Kusanagi (Ghost in the Shell anime version).
Funny enough, in the thread itself there are much more of gaming cosplay than in that nitpick

But still all those characters are well-known worldwide as well as theirs' franchises.
And yeah, every single one of 'em have appeared one way or another in some games, so you're still pretty much right, kinda.. ^, ^
Did everyone win? lmao.
I did

woohoo.
