Okay, nothing surprising about this, since just about every game ever made has a human faction. But both human factions focus almost exclusively on conventional weapons and armor.
Much more here. Both Protoss and covenant are older races (although covenent are actually a bunch of races- it's not a perfect comparison) with much better tech than humans. Both equip soldiers with personal energy shields, and both issue cool energy blades. They both worship the artifacts of a long extinct precursor race. They both make use of numerous powerful energy weapons, and have cloaking abilities. Their legs even look similar.
Both the Zerg and the Flood like infesting people and making them look big and scary and ugly. Both also churn out bloated green things. Both were not properly exterminated by previously mentioned dead precursors. And both become the greatest threat to the galaxy and necessitate a human-alien team-up.
I'm wondering if anyone else is seeing this? Did Halo take some stuff from Starcraft, or did they make it up on their own? And did either of these take similar amounts of stuff from previous media?
And of course, the obligatory question of which of these parallel races is tougher than the other? I figure Terrans vs UNSC is pretty much in Terrans' favor, but the others I'm not so sure of. Also the question of which has the best heroes.
