If they don't want to play it, running it isn't gonna be that fun. That's why I haven't ran the Shadowrun campaign I made for my group. Nobody other than my sister wants to play SR. :/
SR lore is so good and the system has so much potential.
We've switched from D&D to SR4 and BOY does that rulebook have a lot of holes. So many contradictions and omissions, so often things are very unclear. Top that with the insane decision to have the group play basically three separate space-time lines with the real world, the spirit world and the matrix. Let's all wait around the table for an hour while our decker does matrix that takes a second of in-game time and then our shaman projects into the astral plane and that's not as fast as the matrix but still a lot faster and takes another hour but it's only a minute in-game.
We stopped after like 6 months. And it's a shame because the world is so fun.
Anarchy in its original version is unperfect. Consult it before trying to sell it to your players (except if you can read the French version which is kind of a version 1.5)
