What is it? Where do i get it?
What exactly is your problem? What do you want to do?
You can download AGS from the main download page.
The executable of the AGS editor is called "agsedit.exe".
Where have you heard of "Winroomedit"?
You mean room maker? That was the original ags, just get ags it works on almost all computers (exluding macs), very easy to use.
I have compiled the links to old AGS versions here (http://americangirlscouts.org/agswiki/index.php/Adventure_Game_Studio).
Ooh! I'm gonna add that link to the rules sticky if that's all right with you. :)
Sure, go ahead. :)
