I think I'll read it! I enjoy a good world hopping caper, so I'm intrigued.
I've never really been a big Stargate fan - although I liked the movie - so you'll have to introduce a bit of LnC to keep me interested. Every world they ever visited looked like a bit of Canadian forest to me. Wonder why that should be...
Nicely written btw.
Title suggestions:
Stargate: Metropolis.
Universes collide.
Strange visitors (from another galaxy)
Home is where the stargate is.
Wormhole in Metropolis... ok, I'll stop now.
