And maybe a sneaking system that consists of more than just crouching
God, this. This is the single thing I hate the most about combat in TES and the modern FO games. Not only is sneaking this annoying gorilla-walk, but despite the halfassed attempts to be a FPS, FO3/NV didn't even have real crouching, never mind prone or leaning! And it took modders for us to get sprint.
Yeah, I wish Metal Gear Solid was an RPG too.
That's not MGS. That's every vaguely shooterish game with decent controls. STALKER had lean and crouch in 2007 (and finger-twister pseudo-prone, hah). ARMA games, despite their glaring issues, did damned good with stances, especially in ARMA III. Et-fuckin'-cetera.
FO3's stealth and lack of stances is an artifact of Bethesda being used to making TES games, and is one of the few issues that's directly related to FO3 being Oblivion with guns. Stealth should, if anything, be encompassed by stances and movement, rather than an arbitrary and binary system like it has been, especially now that there's no actual stealth "skill". Have perks to reduce sound, allow silent running, whatever (or better yet, don't--take the CS approach and add a "walk" button that removes sound at the expense of slowing movement), but not the stupid bit about squatting = stealth and there's no way to steady aim for long range shots.
Face it, stealth has always been one of the shittiest aspects of Bethesda games. It's typically absurdly overpowered, and it chains into the abuse of massive crit damage alpha strike builds that have dominated their recent games.
