I wouldn't mind seeing something like this although, I think it should use a fatigue system instead of stamina, with the fatigue bar starting out at zero and building up. Once fatigue is maxed anything you do takes a severe penalty hit. Things like, not sprinting, eating, and drinking would decrease the fatigue. It would also, slowly decrease while walking and rapidly decrease while sleeping.

Yeah the agi part is maybe a bit excessive, as much as you might not like it a lot of folks go into these games with a fps mentality and they been really indoctrinated that sprinting tho limited is always a useful thing, adding the whole trip risk is a quick way to make the Sprint button gather dust from lack of use.

I'm fine with it as long as it's player optional. Also, there should be allowances for power armor.

The idea that you would run out of stamina quickly in power armor makes no sense unless you have some kind of temperature/overheating issue.

The tripping stuff might be a bit out there, but I think little stuff like this only adds to the game (imagine yourself falling down while running away from a deathclaw or some such that will surely kill you the second it catches you). I think the game should make it abundantly and unquestionably clear that it is not an FPS (to people that go for it with that in mind) and deliver on that too the best it can; unless FPS is what the game is wanted to be by those making it, in which case all of this has had no meaning anyway.

Why the hell are they* expecting an RPG to be a fps shooter? Why would people buy a game in a series that has been an RPG since the 1990's if they don't actually want an RPG experience and instead want just another fps shooter like so many other games on the market?

Honestly, the best advice that I can give those people that go into the game expecting an FPS, is that maybe they should have looked into the game first or invest their money better in the future. With computers and phones being so available, do* people really buy a game brand new based on the cover without actually looking up what the game is???

I would say you can go into fallout 3 and NV with a fps mentality and a RPG mentality, since it is a fps/RPG hybrid, and in the case of sprinting, most will most likely prefer a fps like Sprint.

Tripping just because you start to run might be a little much.

Tripping as you start to run and happen to be hopped up on every drug under the sun? Heck ya. One of my many fond memories of modded skyrim was pounding a few nord meads to stave off the cold only to trip over myself, fly off a cliff, and die.

Something I noticed after multiple times of having the pc lay on the ground after getting fus-ro-dah'd made me realize how those few moments where you're not in control of your character really seemed to create a disconnect, least for me. It goes from "I have to dodge that!" to "Come on dude, get up, get up!" So eating grass after pumping yourself with drugs I can get behind, but tripping every now and then when you start to run just because your agility is low could get annoying pretty fast.

Maybe a system where as long as you have more than 4 agility you'd never trip when you start to run, but most drugs lower agility beyond the threshold or if you're a natural 3 there's always that chance?

I don't care how its added honestly. If its not i would be one unhappy console gamer!!

It will probably be added and it will deplete the AP bar. The more agility the character has, the more sprinting he can do.

YESSS TO SLIDING! and add diving as well if they add prone.

Like many said already, sprinting yes, stamina no.

Sprinting will depend on your endurance with an minor agility modifier. heavy armor will require more stamina, some power armor might negate this to some degree.

I see this very much as an RPG thing, entirely govern by stats and let players evade FPS moments with character attributes.
