Wonderful 101, I loved Horizon zero dawn but its too similar to far cry and assassins creed, wonderful 101 is the reason why I fell in love with videogames 30 years ago, originality, something totally new, shows a lot of creativity and its challenging, Horizon zero dawn could never win it for me, because on difficult its just too easy. Games are supposed to be a challenge, that was the original purpose of a videogame. Also wonderful 101 is more replayable than Horizon, once you get to the end there's not much reason to restart the game, because you already know the story, but games such as wonderful 101 you could always replay to try get platinum on the levels.
A very close second best for me was Resogun, again, original, creative, challenging, different, replayable
Other new IP that really hit me as very original and creative and different and innovative was ZombiU, the fact that if you die, you die and don't come back, that alone was amazing, the use of 2 screens at the same time which adds to the stressful and scary nature of the game. The fact it was the only survival horror that actually made my heart beat really fast, specially on the survival mode in which you get only 1 character 1 life.
Unfortunately gamers didn't give it a chance, because people got so enamoured with graphics. For me as a huge fan of video games, this generation wouldn't be complete without ZombiU
