In the beginning, there was the Moldvay set of D&D, and I used bits of pen and paper to create my own character sheet. I never really used the official D&D sheets.
Then came the Computer. From that day forth, all my character sheets would be MS Word (or Wordperfect) documents, arranged to my liking. Each would be individualised to my PC; although, I must admit I don't have many PCs, being a DM far more often than a player.
I bought the 2nd Edition character sheets, scribbled in the stats of my main PC, and promptly went back to using my computer-generated sheets instead.
I ignored the 3rd Edition character sheets, and wondered when I would get to play again.
When the 3.5e Deluxe character sheets came out, I decided I'd buy them. Eventually I got to play D&D again, and guess what I did?
I used my computer. :)
However, this is in stark contrast to what my players do. They use the official sheets - either copies of the Deluxe sheets, or the specialised sheets you can get from the Wizards website. (Normally imploring me to print copies of them). There's one player who just uses pen and paper (as I did in the Moldvay days), but otherwise they all really like and prefer the official sheets.
Of course, they haven't had much exposure to the other sheets available, but they're happy.
This isn't just one group of 6 players, either. I have three groups, with some players in common. There's about 14-15 players in my games; and they like using the official sheets!
Now, it seems that Wizards are releasing the Eberron Deluxe Sheets. I guess, being Eberron, the main difference is that they'll have a box for Action Points. :) Oh look, they're bringing back the Adventure Log sheet. (That might be handy for my players, they'll be able to remember what happened in previous sessions. When some of my groups only play once a fortnight, this could be essential).
I guess I'll get them, just to have a look.
Guess how I'll keep track of my characters in the future, though?
:D
