When did they introduce the Deadelus? THat is, what episode was it introduced? Was it in SG Atlantis or SG1?
Anyone remember?
That was such a bitchin’ game, much harder than the original Defender (which still ranks as the coolest arcade game ever.)

Oh, that “Stargate”. Never watched it. 
I’d love to help, but I’m only up to season 5.
The Daedalus was introduced in parallel (or nearly) in each series, IIRC. It was mentioned in the two-parters at the end of last season (“Moebius” and “The Siege”, respectively). At least, I think “Moebius” mentioned a plan to send the ZPM to Atlantis aboard the Daedalus; I know the reinforcements that arrived in Atlantis in “The Siege” said the Daedalus was on its way. I don’t recall any previous specific mention of the ship, although we knew that more Prometheus-type ships were being built. The first actual appearance of the ship is in the first episode of SG:A Season Two (“The Siege, Part III”).
