After nearly a week Finely somebody made a guess.
And got it right, Your turn

Sad, you let some noob (no offense Sefir) with 1 post beat you.
Just sad :devil:

Noob's time it is then :)
Let's try this one...

What are you looking at Cyclops?

Sounds like something Ceville said

Nope SpeedBo!
It's older than you think!!

Another quote from the same game:

She's trying to say "your brain is in a box" XXX.

(XXX is a name. We don't wan't it to be too easy, do we? )

I don't know... i'll take it's some of the classics, possibly with a sidekick looking at that second quote... Toonstruck?

Nope Diego!
However, it IS a mid90's game, I give you that...

Another quote from the same game:
You're giving off a lot of orders for a civillian.

Beneath a Steel Sky?

Nope SppedBo!
But you might be close.... (it is a sci-fi adventure after all!!)

It's been over a week....I'm starting to feel a little weird....

Anyway, last hint:The protagonist is probably (along with Bad Mojo perhaps...) the strangest character you are ever going to play in adventure game history.

Begins with a D. I never played the game though, so I'll give someone else a shot:P

The strangest character... hmmm... He/she is not human? Bazooka Sue?

Nope Diego, it's not that.

Jawa is right however....it does begin with a D. (and Jawa, I recommend you to play it!! It is a...unique experience. If you get used to the strange interface, there are many clever puzzles.)

What's the point of giving hints and not answering by yourself?

DogDay?

No Diego, it is slightly older than DogDay (I never played that. Is it good?).

Another quote from the same game:
There's no such thing as a hopeless situation.

Discworld?

Nope skeeter_93, it is not Disc. Same year however....

(To avoid misunderstandings: The game title begins with a "D", in the same way that, for example, "the Longest Journey" begins with an "L". )

Purely based on the date, the fact that it's a sci-fi, the hint that it starts with a 'd'...I am going to say "The Dig".
I don't recognise any of the quotes though (been a long time since I've played that game).

Edit: Just did a quick AG search from 1995 and found another freaky sci-fi game that better fits the desciption. Never played it though, so no further guesses from me ;)

Thanks for trying Stalkinpanda.....it is not the Dig.

better late than never :P - The Daedalus Encounter
