I'm currently in possession of the 4th edition of Shadowrun and I have many of the released books at hand if I want to prepare a campaign. I don't have a campaign running right now but I'd like to update to 5th edition as soon as it's available. The problem is that Shadowrun seems to require a lot of preparation or at least thinking ahead before you can jump your players in. Specially if you're new at the game. I consider myself new because I only ran one game and it ended after 3 game sessions (player drama). I'm familiar with 4th edition but I really want to prepare some sort of campaign for 5th edition.
Keeping in mind that the setting is not going to be really much different (compared from 3rd to 4th) and I expect every elements from 4th edition to be valid in 5th: How can I prepare a game for an upcoming new edition?
More specifically I'd like to know:
- Planning the campaign arc when you don't know if the character progression will be different.
- Creating NPC. Should I stat them before and convert them or should I simply write the broad strike and note key elements?
