Marvel: Starting in Knowhere

Jack was sucked into an unknown vortex and ended up in Knowhere. To his surprise, he was the protagonist of his favorite game that the devs never completed, and made countless remakes only to abandon them later. Now, he got a chance to play that game in real life and do everything according to his choice, plus its Marvel universe, girls and harem are a must, but then the System popped up with quests and rewards. Complete quests, and get rewards. A simple system without any need for tracking attributes and all.
