I have been a GM of Warhammer Fantasy since the early 90s and a fan of both war hammer 40K and warhammer fantasy world since the same time. I found now myself in need of a change. So many years as a GM in the same setting together with the new edition of war hammer have sucked out my energy.
So after reading some reviews I have decided to try the W40K line for a few sessions.
Which game do you recommend me to start with? and which published scenario (to start with I will run during a weekend 4 to 5 sessions)
Are the rules in between the different books 100% compatible?
I have read that a starting Rogue Trader character is roughly equal to a Dark Heresy character with 5000xp and that a starting Deathwatch character is roughly equal to a Dark Hersy character with 12000xp. Does it mean that with a few modification characters of one book are compatible with characters of another of the books?
