First of mate you should probably fix that channel link of yours

here is a official video that the forum admins made for help on that -
Second of I had to do a bit of reviewing in an IT course I am currently doing, here is everything I know that you might want to speak about in a game review -
Visual Style
- world; Backgrounds, Scenery
-Characters, Non playing characters
- Prospective; 2D, 3D, First person, third person; does this work well with the game?
- Is there scrolling
- is the game context sensitive
- Any Full motion videos ? (FMVs)
- HUD
Interaction and Mechanics
- what can the player do?
- How does the player control their avatar/omnipresence?, are these good controls?
- Customization
- Challenges, Awards and Rules (Feedback interface)
The game world and story
- is there a story?
- if there is how good is the story?
- does it work well with the game?
- does the game need a good story?
AI
- How good is the AI?
- Do they work well for their purpose?
- Difficulty
Audio
- variety
- Quality
- does it fit the feel of the game?
- Too much, not enough?
- how realistic are the sounds?
- are the sounds annoying?
- any narration
Conclusion
- Immersive or addictive?
- Final Rating
- overall good points and bad points
