I think a lot of us have that game where we are just not good at it, but we still keep playing it anyways, much to our irritation. Super Mario 64 is the literal bane of my existence. I really like the game, but I am just so bad at it! I die way too much. I don't think any other game has irritated me as much as Mario 64 has irritated me. The camera angles are awful and I just can't play it. What game do you love, that you're bad at? Why are you bad at it? What makes you keep playing it?
I am bad at every game I play except Pokémon. Seriously. I keep playing stuff like Mario, Smash Bros. and other stuff because I have fun doing it. Or I like the story. Depends on the game.
I love Maplestory, but I'm awful at it. Fighting is not my strong suit, so I just end up button mashing like crazy. However, I play it because it has beautiful maps and stories. It's a huge world to explore with charming NPCs and environments. Despite no longer being a popular game, it was a game I loved as a child and still love to this day, even if I can't play it to the fullest potential.
Gargoyles Quest for the GB. It is like Megaman, but it is more spoopy and it is insanely hard. I was able to finish Megaman, but even after 5 years, I'm still not able to finish Gargoyles quest...
Megaman series...all of them, tbh, even Battle Network I'm terrible at and Smash bros...all of them, but I like playing that game with my friends even though the kick my behind every time that we play...
