Both stories are thrillers that are a race against time as the protagonist has to remember events and people from his childhood to protect himself and those he cares about. They definitely have the same kind of series-long tension that keeps you reading late into the night.

I'm certain Urasawa vaguely based his masterpiece 20th Century Boys in Oldboy. At least the primal concept: in order to find out who his enemy is and why he hates him so much, the protagonist has to look deep into his child memories. Although Oldboy is not a political sci-fi thriller with huge proportions, like 20th CB, it also gives you the same feeling of eagerness to discover the main mystery of the story. The kind of tension that makes you reading chapters one after the other almost non-stop.

Both had characters intent on revenge for something that happened when the characters were kids
The adult male protagonist is presented with the need to look back into their childhood to discover the identity and raison d'etre of the antagonist who once knew him, but now hides their identity. They seek help in remembering the past by consulting other people from the time to try and discover the truths that have been obscured by the passage of time.
