You folks may want to look for a Monster of the Week game. Uses the Apocalypse World system. Easier to dive in (making a character can take about 5 minutes) and the game has very similar themes (you can play a ‘chosen’, a magicy user, a geek, etc.) mechanics are extremely uniform and easy (roll 2d6 +adds: very high is good, avg to high is good with a consequence, low is bad but learn-gain xp). And a given scenario is very tv-like: hear about something bad/a mystery, find clues, find big bad, boss fight. I tried getting a Buffy game going but there just isn’t a large enough committed community on roll20 (with the same time zones, etc.). FYI it was free, weekly or every two weeks any evening of the week. Not one person was interested (or close to my time zone) after 3 months so the community is very lean here. So I moved on to other games... Good luck!
