For the simple fact that what you think will be the ‘true classic’ experience won’t be that still and people will hate that. Also think of the new players who aren’t used to Halo 1 gameplay either, they’ll hate that also. Let’s look at some issues.
Hit scan: As powerful as the Megalo custom scripting engine is in Reach, I highly doubt they can change a core game engine thing such as hitscan to bullet travel. I mean, they’d need to add in all sorts of calculations, bullet animations in air, all this sort of stuff. They can’t change hitscan.
Hit boxes: While I would disagree hit boxes are A LOT bigger than 1’s, they are different. Perhaps more forgiving, or just bigger in some regards, either way, I doubt that can change hitboxes. That is integral on the most integral thing in game, player models!
Physics: You will not be able to grenade weapons your way, or power ups. Physics are once again, a core thing of the engine and recalculating all this…I find impossible with a custom game scripting engine.
Weapons: The AR is 32 rounds, can they change it to 60? I think THAT could be done…maybe…but what about all the other weapons in the sandbox now or weapons that have been changed a lot? Can they make the needler a worthless piece of crap again? Slow it’s projectile speed and tracking? Will they be able to add plasma stun back to the plasma rifle? What about the plasma pistol? What if you hold it in for a charge, will it drain battery like it does in core Reach or not, like it didn’t in Halo 1? What about grenades? Greandes were MUCH more powerful in Halo 1. Bigger blast radius and if you were in the blast radius at all, almost all of your shields were stripped. Will they do this? What about the TSK pistol and the DMR? The pistol in Reach can’t go as far as Halo 1’s could, and I think in the multiplayer vidoc they said they’d keep the DMR in for longer ranges.
Movement: Will they get fall damage right to where you take damage from falling from even 10 feet? What about movement speed? What about your butter shoes where you could hardly climb anything compared to Reach? Will they fix this?
Vehicles: What about the indestructible vehicles? What about the slightest nudge from one and dieing on spot? People who claim they want perfect Halo 1 also want this. Will they do this?
I highly doubt they’ll do the things I mentioned, these were all part of Halo 1, Halo 1 fanatics want Halo 1…they won’t get this. I believe when they realize this, they will be mad and quit again, furthermore I believe newer players to the franchise won’t have any interest in a CoD esque playground, but worse. No bloom, three shot kills with TWO weapons then, DMR and magnum, possible rapid fire 60 round ARs…they’ll want a real Halo experience for what Halo evolved into I think.
But, what about you? I gave my opinion. Give your’s.
