What are some of the good ones? The Adventure Company churns out dozens of them, as do a couple of other companies.

I'm just about finished with Keepsake... I've enjoyed it for the most part, my only complaint is that there are a pair of puzzles that are obscured with these stupid riddles... riddles that have answers that make very little sense... and without solving the riddles, you can't solve the puzzles. For people that have played the game, I'm referring to "Trial #2" and "The Observatory Puzzle." Also, it's a little unclear at times as to what you're supposed to do next. The single most annoying problem with the game is a design bug that prevents you from completing one of the puzzles (even with the correct answer), forcing you to use the game's puzzle solution button to complete it. Really needs a patch.

Anyone have suggestions? Sitting on my computer, I have Still Life and Niburu... I haven't even touched either of them.
