Duh. Do not act offensed, my dear Cardassian.
I will answer that ST and BtVS are too very different approaches of storytelling, and hence, roleplaying.
IMO, in BtVS the tension mainly comes from social interactions. In ST it mainly comes from the phenomena or conspirations encountered, and the way players react to it (which do not exclude social roleplaying, on the contrary - need I remember you the whole Chloe Ellington episode...? which, IMO, is one of the best plot threads yet to be resolved that we have).
In ST, things move along faster, that's all, because lots of people are encountered; the crew is developed, but the goal is roughly the same; the plots very often come from outside the ship. So seasons are shorter. BtVS happens in a city, with many different interests; it focuses on the inside of the city, so time has to be taken to build it and give it verisimilitude.
This is not a judgment of quality, my friend. These are two different approaches, and hopefully I will learn from each, thus getting a better GM for both games...![]()
