playing the piano, I mastered it in around 2-3 minutes, I just mashed the keys and noises started to come out which were just so beautiful to my ears, I even managed to be better than some other people at piano with just some seconds of play, I didn't even play other instruments beforehand and I only learned how to hear sounds in the past couple of months.

why especially aaa and exclusive? is splatoon even aaa? more like aa? I suck almost in any multiplayer game. but I remember playing tony hawk undergroudn 2 online for the first time and constantly getting the highest score (well I finished the single player first).

Vanquish on ps3. and when I was done with the campaign, I went online and was surprised that many gamers found it difficult.

I was pretty badass in bloody roar as Long. 😽

Got to Master rank in Uncharted 4 multi-player as a solo player and without ever being stopped more than a couple of games at a middle rank. I was pretty happy about it, even if I have no idea of the real difficulty of the task.

Mario Kart 8 Deluxe.
It's almost like the game is playing itself, wow.

Oh, I went for fun at a Mario Kart Wii tournament in my town, even if I didn't own the game and just played a bit before. Finished 4th out of 30 players, lost in a tight final. The other guys seemed to know what they were doing though... Most of them brought their own controller and were choosing very specific characters and vehicles, and I was there with the provided wiimote and my Luigi on standard kart... 

I think at this point in my gaming life, every new game is mastered quickly. The innovation is so stale right now that there's never a game I try out which doesn't play like a game I have already mastered three times over.

Final Fantasy Dissidia, Playstation all stars, Soul Calibur, Smash Bros, Souls games. And most recently the BlazBlue Cross Tag Battle online beta I decided to give it a try even though I never played a BlazBlue game before and I got 50 wins very quickly with very few losses. Though im mainly a solo player like 99.9 percent Solo player so its extremely rare I ever try going against people online so it surprises me to see me easily wreck people on specific games.

Crysis 2 multiplayer. I think at one point my clan (at the time) and I occupied like 8 out of the top 10 spots on the Xbox leaderboards. We got our egos so inflated on that game, people would legitimately rage when they had like 1 or 2 deaths in a match. For some reason 99% of the player population just could not come to grips with the cloaking, and the energy management at all. Made for the most lopsided gaming I've ever experienced.
