I don't disagree, but we aren't just talking about how P.T. *controlled*.
That's fair. I kinda parsed your comment out separately from the overall topic, and focused on how GoldenEye and Halo aren't very similar in that regards.
Though I do disagree to an extent regarding PT (as argued above) because we had games such as Anmesia, Condemned, Outlast, ZombiU, Alien Isolation without the direct influence of PT, and I don't feel the genre has been largely affected since. To an extent I feel the same way about Goldeneye being sandwiched in between games such as Unreal and Half-Life on the PC side, whilst the console element (how it controls) didn't change much.
