Come up with an alternate outcome for a game company or series by changing a notable event in their history.
I'll start with a pretty big one.
Super Mario Bros. Is Not A Success:
Super Mario Bros. is for whatever reason a financial flop. Mario becomes mostly forgotten alongside Ice Climber. The NES's top seller instead becomes Duck Hunt. Duck Hunt would later get incarnations on future consoles and inspire Nintendo to bring back some Laser Shooting Systems. Meanwhile, Zelda being the next biggest hit for them would get a lot more attention, and some concepts Nintendo would have otherwise used for Mario games (for instance, Yoshi debuting in A Link to the Past as a horse, Ganondorf having children named after famous musicians, etc.). However, the big money maker comes later in the SNES era with the mostly unchanged Donkey Kong Country series thanks to their partners at Rareware. However, it's not enough to compete with the Genesis, who just barely sneak ahead. The Nintendo 64 is ultimately their final system. Despite their still great Rareware titles and Zelda 64 critically acclaimed, it wasn't as good as it could have been due to it now being the launch title in this timeline (alongside Duck Hunt 64). The N64 is no match for the PlayStation, even more so due to fewer AAA titles from them. Finally, Nintendo merges with Rareware to form NintendoRare Games (NRG), pulls out of the home console market, and becomes a partner of Sega. With NRG's great library and solid games behind it, the Dreamcast manages to hold its own against the PS2 and Xbox, and Sega keeps making consoles to this day.
