Nice idea.

I think it'd be better if someone would talk instead of showing just text and static images.
While talking you could show live examples on some basic stuff, like:

• Attacking someone
  
• Checking which techs are required for certain ships/building/research
  
• How to search for a new colony
  

I'd be more fun to watch that than this.
Also in this clip my attention & interest fades away.
I guess I'd be more fun to watch a live demo with someone actually talking and doing those things.
You could also split up your video's into different parts, basic, advanced, mining, fleeting, ...

i think the idea for this video was to make people interested in ogame .

The following videos can show real play action .

I think they should be very short and specific to a single subject :

Spying : how to spy, how to read a spy report
Attacking : how to select your ships and how to send them in attack , what to do during attack and before impact ( checking if the defender is online or not ), safety spying etc

harvesting :....

ACS......

and so on

As with the narrative part, we need a native English or a native American with very good diction
