The Adventure Trivia Game!

[Rosella]

Ack! T7G! *hides in a corner* The 11th Hour was worse though.

[awesomeasapossum]

You don't like The 7th Guest? I've never played it.

[Rosella]

It's scary. I only remember playing it when I was itty bitty though. 11th Hour on the other hand, I HAVE played recently. I was disturbed on WAAAAY too many levels.

[awesomeasapossum]

But have you played....

PHANTASMAGORIA!

[Rosella]

Bless you.

And no.

[awesomeasapossum]

[Storm]

It's time for a hint! (either that or more off-topic )

Except for the conservatory, in this game you also visit a temple, a fort, a monastery and an asylum.

[awesomeasapossum]

Police Quest?

[Moodyblues]

Um, Sanitarium?

[Storm]

Sorry, none of the above

[Moodyblues]

It sounds like some kind of time travel game.

Oregon Trail?   

[awesomeasapossum]

Dr. Whats his face and his amazing time travelling or something. It was also in the identify the screenshot game...

[Storm]

Nope, not time traveling... not literally, anyway

[Storm]

Still no takers?
I thought it would be really easy by now... I mean, you could just google for the info I gave and get a first-page result

[KingGraham]

Luigi's Mansion? 

[Zelly]

Eternal Darkness: Sanity's Requiem?

Probably wrong, but the clues kind of remind me of that game.

*shivers*

[Deloria]

Amber: Journey beyond (never played it, just seems like a good guess )

[Storm]

Nope, none of those

[Deloria]

The eleventh guest?

[Storm]

No, this game is a first-person adventure, not a puzzle game.
And 'playing the piano' doesn't mean you have to play an entire tune... in fact, you really only need to play one note, which makes this puzzle a bit ridicules
