Mario punching Pikachu off a cliff answered a question nobody knew they were asking.
HAL Laboratory's Super Smash Bros. on Nintendo 64 took beloved Nintendo characters and threw them into a fighting game that broke every rule of the genre. No health bars; instead, damage increased knockback until you flew off the screen. The result was chaotic, hilarious, and deeply satisfying. Seeing Mario fight Link fight Samus fight Pikachu was a crossover event before crossover events were cool. Masahiro Sakurai designed it as a party game, but players quickly discovered competitive depth hiding under the accessible surface. It spawned one of gaming's most passionate competitive communities.
Example
The original Smash Bros. was nearly cancelled by Nintendo, who thought the concept of their family-friendly characters fighting was off-brand. Sakurai and Satoru Iwata developed the prototype in secret before convincing Nintendo to greenlight the project.
Why it matters
Super Smash Bros. invented the platform fighter genre and proved that crossover games could be both commercially massive and competitively deep. It turned Nintendo's character roster into gaming's most valuable IP ensemble.
