I still think about the final case of Ace Attorney 6 often. I had felt that the series couldn't shock me anymore after all the crazy stuff in 1-5 and both Investigations games, but BOY was I wrong. Absolute jaw on the floor moment.
Ive not yet played 6, Im excited to see how that turns out. I love PW final cases, I replayed 2 just a month or two back and its still so damn good.
In terms of plot twists - I still content that Killer 7 has the coolest moment in any game I've played. Its years since it was released and its still the first thing that pops into my mind when this sort of topic pops up.
Game reveal wise - Shenmue 3 existing. And when playing the game, going to Bailu Village for the first couple of times. A real amazing moment I've waited two decades for and literally dreamed about at one point. Game quality aside, its still a great moment.
More game reveal stuff - but back around 2011/mid 2012 (I forget exactly when...) but when Yakuza 5 was being shown off in Japan in its early stages they released an article showing off several new cities and were like "which do you want to see" which was exciting. And the real cool moment is when they just straight up included all those cities in the final game. 5 in general was insane content and quality wise, the only game to even come within touching distance of it combat and content wise is Lost Judgment, and even then, it still misses.
But for pure gameplay/reveal/playing for the first time... its still Mario 64. The control, the rippling in the Hazy Maze pool/paintings, and just seeing a 2D game series move to 3D. Its still unmatched.
