Plus other ancient gods and goddesses worshiped by other cultures.
The popularity of SG1 is that for every Goa'uld they kill or depose from power, there are other interesting, sinister, etc. Goa'uld's that take their place and have their own agenda and earth history. Maybe in Season 8 of SG1 they will finally meet the Furlings.
The challenge for SG:Atlantis is will the Wraith offer the same variety of villainy, what new or old earth mythology will be explored and explained, and since the Atlantis team is rumored to be less military oriented, are they just explorers in a new galaxy? Why are they there? What is their mission? What technology do they send back to Earth? Are the Re'tu related to the Wraith, like the Goa'uld and Tok'ra are? Or have other earth gods/races, besides the Ancients, migrated to the Pegasus Galaxy and are doing battle with the Wraith. Not all gods were perceived as petty, uncaring, or evil.
