Wish fulfillment is one thing, but really? Why not just give him magic nanites that can do anything if you want to go this far. He doesn't even NEED to be smart or have the other advantages you gave him if you keep giving this Gary Stu everything at every turn. You can't, in one breath try and convince the reader that this is a hyper realistic situation, where the supporting characters "health bars" are irrelevant, because everything works so realistically, while elsewhere, your self-educated orphan anti-mercenary pirate hero protagonist, respected by nations, feared by bad men, and unknown to anyone that doesn't need to know, before even encountering the system, creates a one-of-a-kind supercomputer megadatabase handheld smartphone loaded own with hundred year old global street maps and a super gun made out of special alloy, that fits in a backpack, shoots sniper rounds, with a silencer, and can be converted to shoot ANY round and needles (a railgun). Yes, that was a long sentence, butohmyfreakinlordwhattheheck!

... not even going to address the inconspicuous backpack that luckily happens to also (in addition to phone gun and bullets) have had at least water, snacks, spare clothing, a bulletproof vest, elephant snare, eye-stabbing tool (maybe, unless his super martial arts prowess let him do this with his finger), a mask... or the ready-made magic paper contract that appeared from thin air, ready for Faustian bloody thumbprints.

You may not like racists, but making one group in a story ridiculously racist can also be racist if you are consistently using the same race as villains. Example: making someone throw around racist comments, and immediately use racist insults when speaking with the first authority figure they see, someone who descends from a magic portal onto a podium, is both unrealistic and insulting to readers from that demographic and/or anyone with half-a-brain. Im going to bet that these exceptional people, chosen from all of humanity, when they meet a godlike being, if "god" is a different race, aren't going t ask for a ticket to hell just because they were previously intolerant.

Never been struck by a fist or weapon once; he is so overpowered everything he encounters is trivial. He has more chaos points than he could reasonably spend, acquired effortlessly because he can repeatedly see the future, he can buy skills and gene elixirs to get stronger. He has more women than he could ever bed in a day, even if he did nothing else and played two or three at a time. He isn't in danger, or even the threat of something bad happening someday. He, goes on missions because he wants to get stronger... just because he can (no requirement that he couldn't instantaneously and permanently buy his way it of). The story is already pretty meaningless.
