I want to say something like: number adventures?

[All that hate's gonna burn you up, kid.It keeps me warm.]

OK, I will do a quick one.
All that hate's gonna burn you up, kid.
It keeps me warm.

Cool. Anyone can take my turn. I have a couple of busy days ahead of me

That looks like Robert Mitchum and Kirk Douglas so I will guess Out of the Past?

I can answer of few of these:
Scaling objects? You can either create the actual size of the graphic and load it as a separate sprite or put it on its own walkable area and set scaling there. I believe if you do that you also have to change a setting in the object to tell it to "Use Scaling"
Changing the graphic? All you do is set the object's Graphic property to be the new sprite id.
Object in front or behind, just set it's Baseline to be higher on the screen to move it behind other objects, lower to put it in front.
Only way to position or hide objects if you are not in the room is set a variable that will be used to control the object and in the Load function for the room make the adjustments according to the value of that variable.
Creating object in another room you would have to use the idea just mentioned by setting a variable and referencing it in Room_Load.
Creating a Character in another room you can just tell that character to "ChangeRoom".
You are correct that you would have to have the objects in every room that it could be created in and just set its Visible property to be false if it is not supposed to be in that room.

Ancient Art of War?

Correct

cool. here is an oldie i used to play.

But this game does involve space marines.

That is kind of obvious from the screen shot "Deploy Marines".
I am going to guess Aliens?

Is that the next screen shot? Is that from a movie called Bingo?

Thats ok Mandle, you can take it.

Looks like an old movie and looks mysterious, so I am thinking Alfred Hitchcock so I am going to make a few guesses.
Number 13
Blackmail
Murder!
Number 17
Secret Agent

Is that American Made?

the whole purpose for the Game.DoOnceOnly is for this purpose. Even though Danvzare's method will work, the way you had it works also and you don't need to set up the additional variable.
