I think it'd be a good feature for FO3, but I don't miss what isn't there. I never approached it as an FPS, and I don't generally play FPSs like CoD, or MoH... the PC is too slow (as with FO3), and the sprint is too direct and unrealistic, you can't sprint and turn in one motion without the sprint being interrupted back to the slow-ass crawl you're forced to move at at all times. Whilst the freedom of shooters like Unreal and Quake aren't realistic, they're closer than the CoDs and MoHs. Feels like I'm wearing a straightjacket when I play those. "FPS" for me is strafe-jumping (not realistic) and high-speed gunning (more realistic than the CoDs and MoHs and Crys) though... so... meh.
FO3's aiming works for me, third and first person. Aiming decreases the chances of stray shots by a long way. Can't say I've ever had shots at the head I'm aiming at (not just putting the crosshair over and firing from the hip - but aiming at) move to the target's torso instead. That does sound odd. For the Hunting Rifle and 10mm at least, even in third-person, when I aim and shoot without VATS, I tend to hit whatever the crosshair is on. 9 out 10 times that's the head. With less than 100 Skill in Small Guns more often than not many shots go astray, with seemingly no apparent logic beyond the skill level thing, since my crosshair is on the target's head and I'm pulling the trigger. Not much I can do beyond that as a player. lol
Those stray shots do creep in occasioanlly even when you have max skill though, and it's frustrating when using the Hunting Rifle which has a slow rate of fire, and the AI - if not toting a big gun and standing stock still letting fly - just runs right at you and closes the distance in no tme flat with whatever weapon in hand. The video linked in one of the posts isn't a real reflection of anything except animation skewing the effectiveness of the AI.
If that was a video of an FPS the enemy would be spinning on the spot or even flipping to face the PC, with no animation. At least the Mutie is taking steps,constrained by the world he occupies, he just isn't as a BOT would be in most FPSs, blessed with the ability to change tactics whilst toting a Big Gun and lacking other weapons. I reckon once looted he'd have the minigun, some rounds of minigun ammo... and some Ant Meat, probably. If they were all equipped with melee to switch to when the PC gets too close... that video could have been avoided.
I'd still rather see enemies being physically restricted by weapons and forced to move accurately, rather than spinning on the spot with no effort and drilling a couple of hundred rounds into me with a Big Gun as with most FPSs.
The "having to stand still to reload a weapon and still take damage" thing? Not sure why whoever said that doesn't just hotkey an alternate weapon and save on the reload time by bringing up a 'sidearm' as they mentioned, or a better weapon if one is handy. S'not a problem for me flipping from HR to 10mm or scoped SR or magnum. Usually when I encounter different enemies you'll see the weapon on my PC's back change before he even pulls it out to fight. S'no point drawing a Hunting Rifle when there are several ghouls coming at you, 10mm will deal with them more rapidly and has a faster rate of fire. Right gun for the job against more enemies than the rifle would be. *shrug*
