It probably is important historically for console gamers who didn't really play quake or counterstrike online at the time(me), but played with their friends and family, the best part about goldeneye was multiplayer with friends with cheats enabled, so you could have your friends running around with huge heads. It had a very different style to halo which would come later I understand (I never played halo as I didn't have an xbox). It also looked amazing, for the time, had missions, which would eventually become a mainstay of first person shooters, although it does seem like half-life likely was in the planning stage at that point. It did feel clunky at times, even then.

I used to think it was the greatest fps ever, until I played quake-like games in my college years (well after it was a thing, when arena fpses were dying and before the advent of overwatch and eventually fortnite), and I realized how intense fpses could be while not being a point and click adventure (sorry cod fans, that sort of thing is not my speed).
