Here's an idea for the dungeons.Instead of the regular monsters like the skeletons, zombies etc. why not all humans and some monsters added.Like make his dungeons follow Spider-Man games. His gamer system gave him a spider suit so maybe make it spider-centric (hope I used it in the right context).The people he could be fighting in them are gangsters like the Maggia with Hammerhead the dungeon boss, silvermane's crew with silvermane the boss, the Russians, Jamaican's with Bushmaster, Mexicans, the tank top bros from Hawkeye, the demons from ps4 spiderman, Norman Osborn's silver sable security group, Wilson Fisk's group with kingpin himself, the Goblin nation, etc.Even make really hard dimensions full of inheritors or even sinister six.You could make villain dimensions where it's full of the same villain but different versions of them from different Earth's e.g. A doctor Octopus dimension with Tobey Maguire Spider-Man's Otto Octavius, Into the Spider-verse's Olivia Octavius and other versions etc.A green goblin dimension with Tobey Maguire Spider-Man's Norman in a suit and glider, Spider-verse's green goblin who has wings and breathes fire, Ultimate Spiderman cartoon green goblin who just looks like a goblin but has no fire powers or wings, just a glider etc.For the drops or rewards for finishing the dimensions he can get tech like from his ps4 spiderman and ps5 spiderman 2 games like the one that keeps the goons floating, the drone that shocks and disables bombs, sound muffling, the tripline, extra mechanical spider arms etc.
