How do i describe a computer game?

I have to make a 1 page description of a computer game that I've played. I know that describing a game isn't the same as reviewing a game so I need some help. How do I make a computer game description. I'm not 100% sure about the game but I think I will do it for Assassin's Creed.

P.S. - Not review! Description.



Thanks.How do i describe a computer game?
Talk about what you do in the game and things like that... what the game is about... just dont say things like this game is good or this game is awesome cuz thats opinion not description.
