As someone who played Half-Life 2 first, and at the late time of The Orange Box no less, I do find the crouch-jump weirdly unnatural. I’ve never liked it really, as the idea that my character is tuck jumping into vents looks completely ridiculous in my mind’s eye. I guess it’s a technique that sort of “emulates” what in real life would be pulling yourself up onto stuff with your arms, but… yeah it’s weird, and I don’t see why people defend it as a necessary component of challenge to the game. I mean do you honestly think the game is “harder” for including it, and if so, that is somehow a good thing?
I also don’t get what all these people saying “Source games have always used it” are talking about. I play Half-Life 2, Episode One, Episode Two, Portal, Portal 2, Left 4 Dead, and Left 4 Dead 2, and I don’t think the latter three even allow crouch jumping. HL2, the episodes, and Portal never require crouch-jumping once, and I don’t recall ever feeling the allowing my entry onto higher objects with only one keystroke was ever patronising or somehow needed an extra feeling of control.
Considering the game used the HL2 style rolling/throwing for grenades, I don’t think it would be tarnishing the original game to update the movement to feel like Half-Life 2.
To be honest as someone who adores Half-Life 2 but could never get into the original game going back (the things that define the Half-Life series for me are the physics play and memorable characters, both things the original lacked, despite being groundbreaking in its own way at the time), I always saw Black Mesa as basically bringing the original up to HL2’s standards, so the presence of an age-old technique such as crouch-jumping felt really strange to me. Granted, I’m not the only target audience here, well aware of that, just saying.
Honestly I think the ideal solution would be to have some sort of options screen item that activates/de-activates a script that auto-crouch jumps at the points where it is necessary to progress through the game. That way HL1 veterans can keep their manual crouch-jumping if they want, and those who were introduced to the series in HL2 have the option of keeping the experience consistent.
Granted, I don’t know how difficult it would be to put in, but yeah.
