People forget there are issues with Halo but then again people forget the issues with Half-Life as well. The constant remakes help obscures the issues.
It should also be noted no one builds shooters with Halo or Half-Life controls either.
There are issues with everything ever made. What's your point?
Controls are secondary. Every shooter in recent years gets the 2 weapon system, health regen, a grenade button and aim assist. That's a bunch of very meaningful innovations popularized by Halo: CE. Because of those innovations many people now prefer playing shooters on consoles. Something unheard of before the first Halo came out.
I know you aren't being hostile but the question comes off as "huh?" The question was about the "reverence" of some classic game where a comment was made about how it plays and there were loads of problems with those games where design has come a long way (pacing, layout, etc). It isn't so much a problem but a recognition the change in design over the ages. To suggest "controls are secondary" is kind of flippant because this is the interface the real world person has to the game software. As I wrote, no one has these layouts (either Halo or Half-Life) for a good reason.
