Ok some I found:
Gui Montag (Hero Fbat): Main character of the book Fahreinheit 451 written by Ray Bradbury. I read this book in the 9th grade.
(8)The Killing Fields: Based on the actual movie. I saw this in history class in the 10th grade.
Protoss shield system..might be a copy of Independence day's alien sheild system
Ygdrzzgil (sp!!!) is a mythological character from somewhere...
Its the tree of life in norse mythology or something.
EDIT: Alan Schezar is the name of some dude from some anime with a long name that i cant spell...
And then there are all of the obvious similaritys between starcraft and starship troopers.
These are not coincedences but I doubt thge sheild one.There are alot of stories and books with sheilds.
Alan Schezar - Escaflowne
Yggdrasil - Norse Mythology (a huge ash tree in Norse mythology that overspreads the world and binds earth, hell, and heaven together)
click on an overlord a lot and it will say : VISHHHNU! (Vishnu the hindu god of which preserves the world)
The science vessel sounds like Mr. Burns...
I'm gonna skip the above posts...
Arcturus is some bear constellation
Yggdrassil is a Norse Tree, I think.
Magellan is some guy that was an explorer or something like that
Archon: One of the nine chief magistrates of ancient Athens(from dictionary)
Templar: A holy knight, related to defense of holiness, and search for the Holy Land, I think
Corsair is ship used by pirates, or something like that
That's all I remember.
Valkyrie - isnt it like a death spirit? like the grim reaper?
Of course there are these things. Blizzard borrowed it. For example, look at Star Wars. Look closely. Find all the things George Lucas essentially "borrowed" form real world.
Degobah = "Bo - de - ga - Bay", syllables rearranged". Naboo is like Japan in it's art (face paint etc.)
Valkyrie - Norse Mythology, Virgin that takes the Vikings to Valhalla (Norse Heaven) when they die in battle.
Magellan - The man who tried to circumnavigate the whole world but died in Indonesia. His crew made it back though.
The Wakka Wakka map is also PacMan.
Ahh, Legacy Weapon got the thing about Magellan and added more detail then me.
A LOT... xD
