Well since you're opening the floor like that. The moderate marksman thing is arguable, depending on the player Gordon Freeman can perform absolutely ridiculous, impossible shots, doing things like engaging in long distance sniping duels with a pistol that isn't built for precision shooting and whatnot. The high intellect and PHD might be a thing on paper so hey, technically not wrong, but let's not kid ourselves, Gordon is an errand boy. He carts shit around, he pushes buttons, he plugs stuff in and turns valves, he doesn't do science, he does basic puzzles and serves as muscle for the actual scientists. The crowbar thing's fine.

Gordon Freeman can indeed age and he's not perpetually protected from death. He doesn't age between games because, you know, he's been stuck in a timeless limbo since destroying the Nihilanth. He can also die and fail, it's just that to actually see the end of the game you must keep trying, but Gordon can indeed die. The G-Man might stack the deck in his favor on occasion, but things imply that yes, Gordon did the shit he did on his own and had he failed the G-Man would've likely found another subject. Being unable to decide what happens to him, fair enough. The weapons are okay, missing out on some fun stuff but I'm sure they'll come with upgrades.

Of course we could start arguing about whether actually bringing in Gordon himself is a good idea given his status as a non-character with zero given dialogue and personality whose everything, far and away, is ultimately determined by the player in a range most games that tout player choice cannot match. Even the iconic Doomguy had a given personality and mindset in his game's manual, while Gordon Freeman's everything is the player behind the screen. And while this might allow you to technically play something canon as you like, if you're going to self-insert that hard I feel as though making a Half Life fan who got sucked in and got Half Life related powers would be a better idea. Can't say the same thing about Samus because she's been given a manner of personality and sense of self, however slight.
