I ejoyed the Shows most, whre the Cast had a great Chemistry, with interesting Characters.
Lets say every west Marches Episode with Dr. Grigori and Galahan.
Balance of Power, mainly because Jesse seemed to take it always this one Step closer to absolute insanity.^^
I really Like Court of Swords for Dan and Gassy,
The System which is played, plays a minor Rule for me. I like DnD 5e, because u can ususally immediately see the result of a Roll and interpret it.
I couldn´t do that wit BoP, but as i said, watched BoP for the great chemistry of the Cast.
I am relativley new to the Channel, subbed for 15 months, i think. I have never watched the earlier Shows.
So pls excuse if i can´t include those in my Answer.
Just listening to the dark heresy Episodes in my Car, that show was fun, too. so far.
