I'll take a look at the achievement suggestions, but when suggesting things please keep in mind that quests like Throw It On the Ground! and items like Mark "S" Boomstick are not intended to be part of this achievement-only guide :) The Boomstick is covered here: http://www.wowhead.com/news=225727/pop-culture-item-references-video-games-movies-and-tv#movies
You forgot to add the stargate references
While there are Stargate references, I believe they are npcs/quests and not achievements.
How about Kazra'Jin? The guy's a total reference to Blanka from Street Fighter.
All im saying is that you missed a ton of soul eater stuff, though Im probably looking too much into things...
Puddle JumperIt's a referance to stargate atlantis. There is a type of ship called puddle jumpers. Becouse gateship is a horrible name.
As mentioned already, It's Over Nine Thousand!, is a reference to Dragonball Z http://www.youtube.com/watch?v=QsDDXSmGJZA.
How did they miss, It's Over Nine Thousand!/its-over-nine-thousand?
oh yeah, there is no achievement tied to it. but throw it on the ground is pretty funny!
I think 'Eclipse' being a Twilight reference is a stretch, 'Hail To The King, Baby' I expect is also in part due to Duke Nukem, and 'It's Not Easy Being Green' would be from the Muppets, not Sesame Street.Also forgot "You Made Me Bleed My Own Blood" You Made Me Bleed My Own Blood from Dodgeball."You Said Crossing the Streams Was Bad" You Said Crossing the Streams Was Bad from Ghostbusters"Double Dragon" Double Dragon from http://en.wikipedia.org/wiki/Double_Dragon
I'm also not convinced that Eclipse is a Twitard reference. It had a book offhand though.
All of the Klaxxi buffs in Dread Wastes are all heavy metal songs, like Master of Puppets is a Metallica song, Angel of Death is a Slayer song, Painkiller is a Judas Priest song, etc....
It's missing quite a few achievements but it's still a nice compilation, although bittersweet at times. RIP City of Heroes ):
Its over 9000 is also a Dragonball Z reference or did I miss that
The achievement "Stormtrooper" could also be a historical reference
awesome! many things I didnt know they comes from games! thanks! this is great!
