The only thing that has been thoroughly established in the ring-around circus that is DH1 vs DH2 so far is that both "systems" are ridiculously similar to the point the differences are minutae. There are next to no mechanical differences in the functionality and methodology of either. The devil here is in the details. Some people see these details as an improvement, others as a detriment.
This is really the core point here. DH1 is really showing its age at this point, and is separated from DH2 by nearly a decade. Yet while other games in the genre have made advancements in mechanical elegance, DH1 and 2 are different only in minor aspects. They're more or less the same game with some of the more glaring math errors patched over.
I can't say I'm surprised! Signoftheserpent has "Hated" everything I've seen him post in since DH1! He has earned at least a couple of reports for personal attacks when you don't agree with his take. This is not news.
I do have a question for Sign and a couple other's in his camp though: You guys "hate" the entire 40k RPG or so I'm led to believe at least. In one case, The poster even derided the Original 40k TT rules as bad and continues to pound on the 40k RPG. If this whole thing is so distasteful to you guys, why do you still play? Why do you bother with us peasants on the forum?
I'm just sayin... I've walked out on games I didn't like before. Why don't you?
I can speak only for myself and the people I play with, but we really, really enjoy the setting and themes in the game. The 40k universe is well known to us and I haven't found another game that has, as part of its core conceit, the futility of trying to do good baked in to the degree Dark Heresy does. One mission may go well, but at the end of the day there are endless horrors still left in the universe and eventually your luck will run out and if you're lucky it will be a bullet in the head. If you're unlucky you will become one of the monsters you hunt and not even realize it. I really like that.
That said, the rules for most of the game are garbage.
Also if you could link to serpent's personal attack posts that'd be swell, because the only times I've seen the personal attack rule invoked is in cases of someone posting something stupid and getting called stupid for it.
