OOC Discussion II
First, got the post out. Sorry that took so long. (New maps are up for 0 & 1.)
Second, puzzles and riddles? I enjoy them in general (I loved doing the logic puzzles from the old crossword magazines and I do a couple daily crosswords online these days, plus Sudoku is fun), but I'm always a little wary of them in an RPG setting. If you make it too obvious, there's no drama; if you make it too obscure, there's no chance of success and the players get frustrated (that's one of the reasons I stopped playing the Kingmaker online game for Pathfinder, got tired of the tedious obscure puzzles). It's hard to find that sweet spot in the middle.
What I like to do is to sometimes show the framework of the puzzle, and allow the players to have their PCs figure it out by making the appropriate skill or intellect rolls. That way, there's still some chance of failure without having to dial in the difficulty to the players' real world knowledge.
I'm running a murder mystery in my online Star Trek campaign, and I'm having to do this same kind of balancing act. Can't make the clues too easy, but can't make them too obscure, either, since, you know, the players themselves aren't necessarily investigators (or mystery writers). I try to have them let the characters do the heavy lifting.
