Any comments from the catalyst people? Is statting out old adventures and stuff stomping on your intellectual property or just cool fan doings.
He'd have to actually get copies of the books to actually play the games.
Though, come to think of it, you could just play the game with stats as written. That'd leave you with a lot of magic 6 magicians and generally higher stats/skills. But it'd play.
Or you could just run everybody through the conveniently provided SR3 to SR4 converter
http://www.shadowrun4.com/resources/sr4/sr3_to_sr4.pdfThat, in my opinion, will work pretty well for the other editions too.
I think your only problems would be when they have some specialty critter or something and they give a damage code as 5M1 or something and you don't know what to do.
Ummmm that's a bit harder.
Oh, one other thing. The world has generally changed a bit. In SR4 there is a whole lot more matrix stuff and basic magical wards are sprinkled all over. So you'd have to just add that stuff in as approprate.
