OK I have to think this is parody, I made a transcript starting at 5:55: 

I wouldn't really bother getting the 3DS because the PSP does that job [Note: of having lots of games] really really really well, and sure the 3DS has got both an analog stick and a touchscreen, but you know, but you know an old-school, or a hardcore, gamer like me wouldn't really care for the touchscreen.  I mean, you're touchin' the screen, that's completely different to what you do on older systems, it's basically an alternative control.  But now that they have the analog stick, they've basically stolen that from the PSP.  Yes, so in my opinion the 3DS is basically just a ripoff of the PSP. 

Um, basically stolen some of the stuff that make the PSP unique from the PSP [DS], if you know what I mean, put it on their console.

C'mon Nintendo, why d'you have to keep stealing ideas?  Why d'you have to keep stealin' ideas from other companies?  The analog stick -- PSP had that before the DS.  And why the touchscreen, why d'you need a touchscreen.  The touchscreen is just cheap plastic. 

Um ... so, yeah, this has been my video of why I'll not buy a Nintendo 3DS.  Because it still sucks.  I mean, even though it's a later generation than the PSP, it still sucks.  They have improved the DS, the 3DS, somewhat by making their graphics more 3D -- that's why it's called the 3DS -- but the PSP's graphics are 3D as well and I don't think they've improved it enough to beat the PSP. 

Key points of hilarity:
-- The idea that the 3DS is stealing analog from the PSP, instead of both of them stealing it from consoles.  The kid keeps beating us over the head with this one over and over and over again, remember this is only the last part of the video and IIRC he spends the first couple minutes on that subject as well. 
-- Equating the actual 3D appearance of the 3DS' graphics to the 3D graphics of the last 15 years.  Even for a kid this is such massive intelligence failure I find it hard to believe that someone who would make a video like this would fail so utterly in his research. 
-- "Why do you have to be so unoriginal Nintendo, and also WTF am I supposed to do with this control system I'm not used to?"

I mean seriously, is this kid a member of SDF Youth or what? 

And I didn't take notes on that Mario video, but wasn't he talking about the early '90s as if he was ... alive and aware of current events at that time? 

I would never approve of child abuse but...

On the Mario sucks video, he talks up Super Mario 64 because it was the first 3D mario.  I think this is what the kid thinks for 3D maybe with the 3DS?!?  I don't know.  That's all I could put together on that from the Mario video that was added to the thread.  Maybe the kid doesn't understand 3D?  His parents moved him to the garage for goodness sake.  His next video will be why Ninty stole Move and it will be filmed under the stairs me thinks. lol

a young john oliver if i ever saw it. :)

Basicly Nintendo couldn't use analogs, couldn't improve graphics and couldn't keep the touch screen to make him happy...WTF?

Oh, and he's hardcore remember! He started playing during the PS2 era so he's an old school gamer!

Normally I joke about the British and how they "butcher the English language" (even though they are the very source to the language I speak today)....but his accent annoyed the shit out of me after 10 seconds, and I closed the tab on that video

Well, this was bound to happen with both Sony and Microsoft releasing franchises such as Halo and God of War. The kids who grew up playing what they dub "hardcore" games that their older brothers play are franchised by either/both Sony or Microsoft at the expense of Nintendo.

Bound to happen, every kid can't grow up being franchised by Nintendo with the usual Mario, Zelda, Metroid, Donkey Kong, and Star Fox series. Those of us who did, grew up in a simpler time with more age appropriate games. Nowadays you have bad parents who want little Johnny to shut up and not be in their face all the time throwing fits, therefore they go out and purchase him the latest Grand Theft Auto game.

I am with Final-fan on this one. The video itself is the troll. Kids older brother probably finds this all quite hilarious. The old school gamer is the give away. I am amazed at how well it worked though.

I wish I was as old school as this 10 year old kid.
