zeogold: So, let me get this straight, the way this works is I describe the point I'm currently at in a game from GOG (or just any point in the game in general?), then see if you guys can guess it? I'd be happy to volunteer, unless there's already somebody else ahead of me. I AM the Puzzlemaster, after all. Distributing puzzles is my forte.
Not necessarily. :-)
You can describe the characters, the setting, some other in-game elements (there were puzzles like "I am a mercenary who fancies hiding in boxes and stealing enemy equipment and staff by means of airlifting those"). Describe it in a way that makes the game recognizable to someone who has played it in any way you like.
Certain points in the game are a viable option, but not the only one. And yes, it doesn't have to be a game from GOG or, for that matter, a PC game at all.
Also, if you take it upon yourself to be the "puzzlemaster" for this round, bear in mind that this forum game varies greatly in pacing, sometimes a puzzle may be up for several days, sometimes it takes mere minutes to guess the game and move on to the next one. Speaking of the next one, that would be determined by the one who guesses your game, unless (s)he chooses to pass the turn.
