What is one game you can truly say you are good at?

I'm really good at playing nukige visual novels :^)

Jokes aside: i think i'm pretty good at Contra for the NES, i was able to do a one handed playthrough when i was 19.

Captain Claw I guess, it was my only game for some time back then so I got plenty of time to master it.

Super Metroid. I used to speed-run it in my teens. I'm probably not nearly as good at it these days though.
Majesty: The Fantasy Kingdom Sim.
Shadowgate (I pretty much know that game by heart ;) )
Probotector/Contra

I'm generally relatively good at games. Comes with having played a lot of them ;)

No game. But it does not prevent me to like many kinds of games ! :p

I would´ve said OFP ... but that one night we played with CTI veterans was kind of a vision shifter XD

Agricola sadly this doesn't exist in videogame form :/

I'm usually good at turn-based, grid-based things (roguelikes, 4X, tactical stuff) and meh everywhere else. Lots of people praised me for finishing God Hand in Hard (apparently that was supposed to be pretty hardcore, although from my point of view it was mostly cheesing the game with canceling and stunlocks) but actually I'm probably of average skill.

ultimate mortal kombat 3 (genesis/megadrive port)

Halo CE using the SPV3 mod. Before my life got really busy I could go entire missions playing on Noble difficulty (the one above Legendary) without dying once.

Right now I'd say I'm pretty good at Rising Storm. I'd say I have a thing for FPS games, other genres not so much lol

RR, S&ASRT, OR06C2C

Halo 3, Halo ODST, Halo Reach, previous PES, unreal tournament, Half-life DM, Day of Defeat

Left 4 Dead 2, Counter-Strike, UT2K4, League of Legends, SWTOR.

I never had the time or opportunity to go professional, but that's just as well.

Need for Speed. Pretty much any racing game honestly xD

Duck Game, I have over 1,000 hours on it and it's my favorite steam multiplayer game so far.

single game? Maybe League of Legends based on my time, but really not good compared to others. Otherwise I'm very good in platformers and puzzles / logic games as I'm very good at learning and implementing new rules.

GoldenEye 007.

Probably any Kirby game. I think I 100% each one I played except for Epic Yarn.

FPS games in general, mainly Battlefield 3 and Insurgency.

Duck Game :3

Call of Duty World at War. I was awesome with bolt action rifles back in my hay day. But, these days i'd say Company of Heroes.

Rainbow Six Siege :) (Sometimes afther 600 hours...)

I'm decent at platformers and twin stick shooters, I remember getting some good scores in Waves.
I'd love to be good at Rocket League but even after playing for over 50 hours I feel like when I win it is out of luck and not skill.
