Destiny is a saga of 2 games. The first called, simply, Destiny has been launched in September 2014. The second one called ,as you can tell, Destiny 2 has been launched 3 years later in 2017. I will speak about the first one.
It’s a MMO RPG videogame. MMO is an acronym for Massive Multiplayer Online and RPG is an acronym for Role Playing Game.
In this game you have to create your character and choose a class for it. You can choose from Hunter, Titan and Warlock. Those 3 classes have different abilities and they make the game more cooperative.

As I said it’s an intresting game because you have to play with your friends to complete missions and raids. It’s funny to play but it’s so long, to complete a mission you have to play 30 minutes on average and for the raids you can play for hours.
I would reccomend it if you are a person thet loves spendig time on videogames and you have much freetime. If you don’t have this time I wouldn’t reccomend it to you.
