Online Game: Starting with an SSS-Level Plundering Talent

I do very much enjoy this novel and think it's pretty good! But that doesn't mean I don't have constructive criticism for you as an author. Let's start with the positives: 1) You pay attention to the math/stats! It always bugs me when authors of LitRPGs mess up the math for stats, skills, damage numbers, etc. 2) The main character still struggles despite being OP. My favorite characters are the kind that are OP, but never OP enough, which requires them to keep getting stronger. Now for some negatives/constructive criticism: 1) The main character, John, has no backstory from before he started playing the game. After he regresses, we don't know whether he has any friends, family, a job, debts, responsibilities, etc. These things are important to forming an understanding of a character and how they became who they are. For example, being an orphan could mean he learned self-reliance and to be tough. Which could then translate into why he never wanted to submit to the gods later. 2) The R18/Naughty scenes, while not bad, are kind of all the same. It's him dominating until she begs for mercy and him not being fully satisfied even when the woman has much higher stats than him. Mix it up a little. Sini is always asking for help, so maybe do a threesome or more. Maybe have him actually be satisfied for once. 3) The world building is very odd and vaguely defined. It supposedly takes place on Earth in the year 2025(meaning next year), but the Earth it shows us is so vastly different from the one we know of. There's noble families that control multiple countries, ancient martial families that are above even them, empires, full-dive game pods that allow people to game for months on end with negative effects on people's health, slavery is seemingly an accepted practice, etc. None of this is explained very well since the focus is on the game world. So, I'm wondering why all this overly complicated world building for Earth is even here. Maybe simplify the worldbuilding for Earth and focus the worldbuilding on the game world. The game world is more interesting anyway. It's not easy doing worldbuilding for multiple worlds in one novel. Novels like "The Death Mage Who Doesn't Want A Fourth Time" prove it can be done, but that's an exception, not the rule. 4) The side characters are not that helpful to the MC John, despite how much they and he tries to make them helpful. It's mostly him dragging them along to level up while they can't help much. They don't have to be as strong as the main character, but they should at least be able to lighten his load. But they can't seem to do that. None of them can keep up with him or contribute to him in any meaningful way. If you want good examples of how to make side characters that are helpful to the main character after the main character invests in making them stronger to help him out, then read any of Toika/Toy Car's novels. All of them are great LitRPGs with side characters that are not just side characters to the main character. They are his irreplaceable partner in battle. They compliment each other for their weaknesses and shortcomings. They know that the main character can't be everywhere at once or take on the entire world by themselves. And the banter between them is some of the most enjoyable parts of the novels! I know this is a lot to read and kudos to you author if you read it all. I write all this because I believe that you have the potential to do even better. This novel is already quite enjoyable, and it(or even another later work of yours) could be even better!
