I would have guessed that #6 is
Spoiler:Still Life, it looks a little bit like the docks in Prague.
But Trunkyo seems so sure, so I suppose not.
(So that wasn't an 'official' guess.)
Also, #2 more or less screams
Spoiler:'Syberia' to me, but that game already has a screen. But the doors definitely look like they're from Valadilène. You know what, I'm going to go ahead and guess anyway. Is #2 Syberia?
I have a guess for #7 as well, but am I allowed to do it now? I mean, this is round 3 right now, but you could only make "belated" guesses during round 2? I'm confused.
And thanks for the quiz Dalilah!
