10 Video Games With Insane Features You Never Knew

Now, the final entry onto this list is a bit of a special case, given that this feature wasn't actually fully implemented into the game as intended, but its ambition is so staggering - and so little-known among players - that it absolutely merits a mention.

When Banjo-Kazooie was released on the N64 in 1998, developers Rare had hyped up a ground-breaking feature which would allow unprecedented interaction between the game and its sequel Banjo-Tooie, released in 2000.

Basically, players who scored 100% completion on the original game were shown three new areas for Banjo to explore, yet without any way to actually access them.

Rare later explained that Banjo-Tooie players would be able to import their Banjo-Kazooie progress into the game via its "Stop 'N' Swop" feature, but the practical realities of this weren't revealed until patent documents confirmed the original plan years later.

Rare boldly planned for players to access these areas by swapping between game cartridges while the N64 was turned on, with the console holding the corresponding game data in its memory until the swap was completed.

It's often said that the feature was ditched because Rare couldn't get the N64 to hold the data in its memory for more than one second, but it was recently revealed that Nintendo of America specifically asked the devs to remove it for a multitude of reasons (stability and safety, primarily).

While the feature was dropped in an official capacity, players have since been able to access the content thanks to cheat codes and hacking, even if the creative lunacy of the original Stop 'N' Swop sadly never came to fruition.
