There needs to be a higher res version of this. I can barely make out some of the details even if I blow it up and squint really hard. I clicked the wrong link.
I can name pretty much every character and game they come from. It's a tad on the easy side if you've been playing any video game in the past 10 years or so, but sadly, about 10-15% of this image goes further back than the sixth generation, which is pretty depressing the more I think about it.
Having said that, I am a mildly amused on some of the more obscure choices, but in the end this seems like someone had an afternoon to kill and Google Image search. There's even a few "characters" that are either nameless or are part of a collective.
And if this person is going to sling around his/her "I'm so fucking 1337" image, (s)he should at least brush up more on hyped games that were never released:

Duke Nukem: Forever and Starcraft: Ghost isn't exactly news to us.
Final assessment: All this "IQ Test" did for me is make me feel old. I don't need some jerkass reminding me that I was raised in an age that's been dead and buried with the rise of the internet. But further looking into it, it seems like this guy just tried to squeeze in every pop culture reference from the past 5-10 years into an image and squeeze every last bit of pretentiousness out of it. Fuck this person.
