well, I did watch this, and while the pilot was blatant copy of the first episode of SGA ( with the exception of the communication ability with earth almost right away)
Lulwut?
They shared some similar elements, however the premise was entirely different, for starters, quick episode side by side (from what I can remember of both)
SGA
-Start on antarctic outpost
-Sheppard sits on a chair, this leads to the gate address being found or something
-About a year of preparation is finally put into use, people chosen flown in, tonnes of supplies at the ready
-Arrive at Atlantis
-ZOMG POWER LOSS
-Send Sheppard and Sumner through gate with people to find power source
-Meanwhile city rises
-ZOMG WRAITH! Abductions!
-Go back to Atlantis
-Take team to X planet in Jumper
-PEW PEW WRAITH
-WE WON BAI
-End
SGU:
-Start on ship
-flashback
-moar ship
-flashback
-ship stuff, LIFE SUPPORT FAILZ!
-flashback
-stuff about life support, senator bla bla
-Rush revelation
-CHRAGE
-The gate dials weeeeeee
-drop out of FTL
-Dial planet
Yes, both involved going through the gate to a distant place, but SGA was planned out nicely, SGU they had to rush through and had extremely limited supplies...
