I don't know what version of HL2 you played, but you get the gravity gun fairly early in the game, in Chapter 5 (there are 13 chapters in total).Half Life 2. gravity gun was the best part of the game and you get it only for the ending.
I meant the supercharged version of gravity gun you get at the end of the game where you could use it kill people.
You mean the one that's actually logically consistent with how it grabs onto pieces of matter instead of just grabbing inanimate objects for some reason
The real logic of course resides in game balance. The end game gravity gun is overpowered as fuck, even the swarms of enemies they throw at you is no match. It's pretty boring once the novelty of throwing people about wears off (in two minutes).
If the Gravity Gun was like that from the moment you get it early in the game, it would be a legit broke experience.
I dont think anyone is arguing that entire game you should have the exact version of the end game gravity gun that instantly kills every enemy, but that the gravity gun had potential to be utilized far better then being just a gimmick for occasional puzzle.
