It took Hollywood decades to learn the truth about superheroes: the origin stories are usually the most boring part. Insomniac Games was clued into that fact from the start with the Marvel's Spider-Man games, which deliberately avoided showing us Peter Parker's fateful meeting with a radioactive Spider. It seems they're taking a similar approach with Marvel's Wolverine.
"During our story, Logan already has adamantium infused to his bones," creative director Marcus Smith explains at a preview event for Marvel's Wolverine. "He does not remember how that happened, why it happened, and we are not really covering it because we're not doing an origin story."
