Pokémon Black Version 2 & White Version 2
DS / Game Freak / 2012
A lot of people usually disregard the final installments in each Pokémon generation as just the same game as before with some minor improvements, and while that was true for most cases, the 5th generation in the series broke from this formula in a fantastic way. Black 2 and White 2 weren't just minor improvements to their predecessors, they were fully fledged sequels that expanded on the great story and setting of Unova, while also adding a ridiculous amount of content to make this the definitive 5th gen Pokémon experience. I was very skeptical when these were first announced, but Game Freak proved me wrong and made me acknowledge they were going in the right direction with the franchise.
