For the record: I hate (yes, hate) the SR/ED crossover and every single bit that smells like it, too. ED as a former SR never worked for me, the concept in itself is broken in way too many places to actually even consider it as anything than a joke or a very very weak marketing tool (from a storytelling point of view, of course EVERYTHING can be explained ingame, much like Aliens versus Predator or Jason versus Freddy or Freddy versus Aliens or Winnie Poo versus Vader).
If you wanna cross two totally unrelated games by the same publisher, play BattleRun. That at least would be FUN.
Sorry to sound like a total ass, and be assured that my eternal and infernal wrath will only manifest every so often by a short outburst like this one, without ever being directed against anyone in particular. Play everything you like, as long as I'm free to ignore the ED/SR stuff (so unless Harlequin gets voted to be the next world president or the Therans start actually popping up or we get f*ing windling street samurais, I'm fine).

BTW: I don't hate ED. It played some sessions, I liked it even somewhat, just not enough to keep playing it (so many systems, so little time). Just ED and SR having anything to do with each other is just ... wrong.
