Well, apparently I posted this in the wrong place originally, so I'll try it here!
As the title says: Have you ever played a game that has annoyed you so much that you just went "Nope. I refuse to do this anymore. I'm not playing this stupid thing anymore."
This can be any game, not just a Pokemon one.
I'll start with Pokemon Shuffle. I have been playing this game for ages, but about a month ago I got to level 150 - Mega Mewtwo Y.
After a month of grinding Misdreavus, Liepard, Chandelure and Mega Sableye to level their maximum level, hoarding all the coins I could get so I could buy the "Moves + 5" "Mega Start" "Disruption Delay" and "Complexity - 1" power ups, waiting patiently for all that time for the stupid heart timer to give me more hearts to play with, and many frustrating attempts to capture Gengar, Umbreon, Heracross, Mismagius, Scizor and Zoroark in the hope that one of them would help me beat Mega Mewtwo (all those attempts failed, even when I paid out extortionate amounts to use a Great Ball (and thus pushing me further away from affording the power-ups)) - I finally took on Mega Mewtwo Y this morning.
I am never playing that stupid effing game again. It really isn't worth the time and effort I was putting in.
Anyway, that's my game, what about yours?
