Can't wait.

I just finished Halo 4 and have been trying to put all the pieces together so this helped me a lot.

Story seems better than I thought it would be.
Im haveing a hard time imagineing humanity within 500years being able to colonise over 800 planets, though.
(id be surprised if we actually have just 1 planet colonised within the next 500 years)

A really good recap. It did not go deep into the whole back story of the forerunners, precursors or creation of the flood, but for a general overview of the games, it was great.

Yeah i agree, Just to find 3-4 golden luck planets will take several years, just as well as producing ships and get a population high enough to send colonists to new planets. 
The travel alone is risky with probably a lot of dangerous obstacles as well as enemies. 
It's hard to do the math when i don't know how many survivors there was left of the human race but from what i've heard, the human race was almost exstinct but based on that alone, there isn't enough time for people to produce 800.000 people to populate 800 planets in just 500 years.. If the numbers are below 500 people each planet it will take a heavy hit on the genetic pool without re-using the same blocks and the children yeah you know. 1000 people each planet with just one colony on each planet is crowdy enough to start a healty new generation of people.  8000 people isn't even enough to populate a planet long enough in 200 years to have enough man-power to occupy 600 other planets for the rest of the 300 years. It's impossible..  It takes years just to populate one planet strong enough to jump to the next-

Wow, thanks for the video! Great recap and I forgot some of the stuff from earlier Halo games so this was useful.

I wouldn't bet on your opinion. Technology take serious leap every 2 years. I do not work nor I'm a specialist about space and engineering, but it seems quite possible to me. I mean, 100 years, i'll doubt it. But 500 years is a lot of time to make the technology advance. I mean in 500 years, quantic engineering will be old-school and this is crazy since quantic computering is quite a leap in itself and will allow crazy stuff in a near future. 

I've played all the halo main games so far and while the story isn't bad at all, the main game fail to make you intersted in it since all you see is some glimpse of narrative. I hate game when you have to pay attention to what is said on subtitles level to understand things, like Gta. The narration in game in halo is really, really bad in my opinion. 

Yeah, 15 minutes is too long.

I just finished up Halo:MCC, so I'm already pretty refreshed on the story. However, this video filled few holes I didn't quite understand.

Thanks for posting.
