I started the "Adventurer's Diary" while playing Morrowind - an excellent RPG, by the way.
Unfortunately, after having finished Gothic and Gothic II before, I had to find out that
the internal diary can't compete at all and misses to store a lot of required (or, at least,
detailed!) information about NPC's, locations and other stuff. If you played the game
you know that "Vivec" is not very helpful to find a person you once met again!
I've been told that the "Tribunal" extension features some improvements, but most of you
(like I did) will start writing down their own "sticky" notes.
In case of Gothic this was seldom needed, and the information you had to remember was much
less complex. Morrowind, however, will quickly make your desk look like a recycle bin!
So I stopped playing and started to care about this problem first, thinking Morrowind would
not be the only roleplaying game in need of a gamer's personal diary.
The result is a small database application that does not only search for simple keywords.
It's biggest advantage is that you can combine keywords into relations and search full
ranges of topics to find the one that fits best - and even see the relations between topics!
This is hard to understand, so I will give you an example:
