I remember a game, in which you were put in a space shuttle and sent to outer space to look for some kind of planet I guess. But the thing was, at the beginning of the game, earth would explode and you were the only human left. I remember entering rooms and trying to find evidence of alien life. I also remember that game always made me worry if such a scenario would happen.
The only thing I can't remember is the name of the game
It was mid 90's tho ...
