I've been rping D and D 4th edition (and yes I enjoy it! *cue disgruntled rants*) but I'd like to do some GM'ing come next year. But not D and D as I'd like to dig my teeth in a setting that appeals to me. (I'm considering Judge Dredd, The One Ring, L5R but also... Black Crusade)

Now I've got 2 questions:

1) How accessible is this rpg to players with limited rping experience?

2) Is it worthwhile to wait with ordering this book? I heard there are a lot of errors, typoes and stuff missing in the book. Is this true? And if so how soon would this be 'fixed'?

1: Fairly accessible IMO but a some knowledge of the 40k universe is helpful (but I guess that goes for the other settings you mentioned).

2: Im not sure they ever fix them tbh, they do publish erratas however that fixes the stuff that went in wrong.

Aaah okay! Thanks!

Accessibility: Well, I would say there is a reasonable llevel of complexity, but no more than d&d has. I would not recommend Deathwatch as a starting RPG due to the various abilities that your character has that are almost impossible to keep track or ("Wait... I get to re-roll pinning checks? When? Where? Oh....") if you aren't experienced (and sometimes even if you are). But then a new player coming to D&D would not be recommended to start at level 20, which can be equally (if not more) complex. Dark Heresy characters are not that difficult to keep track of, and you gradually build up your character so you get to know the abilities as you go along. There are all sorts of special things you can do, but like d&d 90% of the time you never need them and/or your PCs won't bother. Black Crusade is more complex than Dark heresy, as you start with more powerful characters, so you might 1) want to avoid Space Marines, except for more experienced players, due to their various little tricks and 2) go over the various talents and special uses of skills of the players characters before starting play.

Worth waiting: No. It will take forever before FFG implement error fixes and any errata to the book itself. I think the latest version of Dark Heresy only implements the first errata and it is on Living Errata 3.5 (or similar), and it is now at least 3 years old. If you want to play, buy the book, keep an eye out on changes to the inevitable errata and on this forum. Ask questions, check for what others have done, or even come up with your own house rules to fix to taste.

Others are apparently already running Dark Heresy and the likes.
Plus what can I say my best friends are all fans of the Chaos side of things

I'll keep all your advice under consideration though. If it's truly that complex I may go for another rpg I've been considering.

I will say that the games of this line tend to be in the medium range of complexity. While they don't play as quickly as Savage Worlds (which, IMO, works very well for Warhammer Fantasy), they also don't have the same volume of complexity in play as a game like D&D4e (lots of map & mini specific issues that come up all the time) or Pathfinder (pages and pages of rules text that always seem to reference you to another part of the rules that take another several pages of rules text before yet another reference to another part of the rules...).

The complexity of Deathwatch can frankly be overstated. It is no more complex than D&D 4e, although the system is VERY different. My group went from 4e to Deathwatch with relatively few problems, apart from some house rules to make melee combat more fluid (which has been addressed in Black Crusade).

While Dark Heresy is simpler, it is also a considerably grittier experience. If you don't care for high character attrition, it may not suit your taste.
