I can safely write my answers to this round here: "".

Hey! No copying my answers.
In reality though I recognise the character in no. 6, but have never played any of the games so wouldn't be able to specify. I
think I know what series the last one is from, but I'd have to look it up the get character names so that doesn't really count. Nothing in any of the others looks even vaguely familiar, not even in a "I've seen that guy in screenshots but don't remember the game" kind of way.
So far I think 4 is the highest number of games I've actually played in any of the rounds, so I'd probably have been screwed even if the first 3 rounds weren't music based.
