I'm not really a PnP gamer either (only played a few games a few times)
but I love to read them, especially the in game "histories".
With the exception of GURPS books of course, those are actually pretty good reference materials.
WotC is the only company I feel no sorrow for when I see someone pirating their stuff.
Well, that and Acclaim.
But Acclaim died... muhahahahahahahahaha
I don't know about complicated, my problem with GURPS is that it's bland.
Dry.
Dull.
And maybe a little too dumbed down.
Shadowrun is a bit complicated, until you actually learn the system.

DW 3 was ok.
End first story arc
DW 4 was a darn good game and begins the next story arc.
You should start with 4
