Ark survival evolved could be a fun one. He could live his live there and go from island to scorched and abberation. For skills he could get something basic like a crafting system and dino taming and basic knowledge of plants animals smithing even element he could also get corrupted like rockwell or something or go to the path towards ascension like helena there are a lot of options without it being to over powered for in the beginning of the novel.
You could do MegaMan X Series. With either the armors n' blasters from X or Martial Techniques from Z. I believe you know what else I refer too like the mavericks. Could even use the future games with biometal. Or if you want to nab a rougue like dungeon crawler. Look at the indie trio of Risk of Rain, Enter The Gungeon(Look at the different characters), or The Binding of Isaac(The characters with their pocket items, actually you could make these blendible with other classes). There is also Skul the Hero Slayer.
