4. Vastly Better Fights with Wolverine's Enemies, including a 300-Foot-Tall Sentinel that's Not in the Movie at all
Without spoiling the X-Men Origins: Wolverine game for anyone, let's just say that the boss fight against the card-throwing Cajun mutant, Gambit, is hands-down one of the most epic moments in the game. As for the fight against the two iconic characters in the film, well... it's not memorable at all, and is actually one of the weaker action sequences in the whole flick. Wolverine's insanely intense battle against a skyscraper-sized killer Sentinel in the game isn't even in the film at all.
