Atlantis - Hmmm stargate Atlantis so far rings a bell.
Have you ever heard of the 'Lost City of Atlantis'?
But no, it's definitly named after Stargate Atlantis which has nothing to do with the main concept of the Lego series: finding the lost city of Atantis. Yup, definitly ripped off!
Portal - clearly a loving stargate except they don't name it stargate.
portal =/= stargate
Get it through your thick skull.
And I'm pretty sure the portal is more like a really fancy doorway, not something that takes you to other worlds.
And you still are on earth when you come out the other side, alibet underwater.
Fish like human enemies = bing bango, it's there too!
Hmm. Maybe because it's UNDERWATER?!
But no, it's obviously from SA!
