I was trying to think of which games created certain mechanics that became popular and copied by future games in the industry.
The most famous one that comes to my mind is Assassin’s Creed, with the tower climbing for map information.
Third person view in an FPS (first person shooter) type of game was first seen in the first Lara Croft game, I think?
I think you need to be more specific than just “third person”. Third person view was in Pong, Pac-Man, Asteroids, Centipede, etc. It’s the default for most games.
First person was probably introduced with Battle Zone.
Which, I don’t mean to sound pedantic, I just literally don’t really know what you mean here.
Then you will need to extend that to the OP of this comment chain as they didn’t specify either what Gears of War is. I am going to edit my comment to clarify but I do feel you are too pendantic for asking this.
