One of the first things I like to do when checking out a new game is to build a character to see how easy it is to pull off. This also comes in handy when I have to teach players to build their characters as well. That said, the Dark Heresy Character Creation is pretty efficient, with room for both random character generation, and enough wiggle room to hash together Point Buy variants if you have players who abhor the random characteristics rolls. (Honestly I don’t mind random rolls since they give texture to characters. Nobody can be excellent in everything after all.)
That said, I dove in right away into trying to put together a character for the game, picking some options, and rolling for the Characteristics.
