Just for curiosity sake, I'd be interested to see a brief rundown of what Primetide is thinking for some starter missions. Basically the plot lines without any of the secrets. Not sure if any thought has gone into this yet, obviously getting the game working needs to take priority before most of the writing can be done.
And while we're waiting on him, why not toss out some story ideas they could use. Try to flesh them out with the fixers speech to get you there, roughly what equipment might be needed if anything special, where its at, who the run is against, etc. Keep it to basic plots though, nothing extravagant, just beginner type runs to show people whats in the game, and try to include things that will entice old players with interesting tidbits while putting a wow factor in for people new to Shadowrun.
