I love this game, however the one thing I find it is missing is a small Cheat Sheet that list all the characters on it, with a brief description. I find that new players myself included are always taking time to go to the book to see the characters to deduce what someone may have picked.
Are there any good downloadable cheat sheets online?
Character Cheat Sheet
in my edition of the game,
every player gets a little sheet with all characters and all their abilities.
I own the very first version (if there is any other version around)
Germany though
just a very small picture i found with google now:
the cards next to the two gold tokens for each player
You could try

The files section has a number of player aids - rules summaries, character summaries etc.
In the italian version, in the rulebook there is a short reference of all characters(including expansions), anyway try with Board Game Geek =)
