>>42022271>the hate for RBY glitchesThis is purely a case-by-case basis. Shit like moves not working properly, or Toxic and Leech Seed messing with each other, are bad; things like the Old Man glitch letting you duplicate whatever item is in your 6th slot are not, even if they're not intended.
>the hate for GSC level curveBecause you get a decent groove going, then suddenly the enemy levels spike, and then after the Elite Four, they spike again - except now there's nowhere to grind in a timely fashion because for some idiotic reason, all the wild Pokemon and trainers are hideously underleveled. Why the fuck am I encountering Level 2 Pokemon in the postgame? No, I don't care that that's how it was in Gen 1 - it's bad game design. And then you get to Red, whose Levels skyrocket from the previous boss by 20-30, and the area he's in has shit that maxes out at 51.
>the hate for HMsBecause most of them are shit moves that are forced upon you for progression, and you can't delete except with a specific NPC you don't see until near the end of the game. These are all functions that could be fulfilled by items, or just having them be special actions you can teach Pokemon that don't require a moveslot.
>the hate fro Hoenn's water routesThey're all incredibly similar, and you only ever see like three Pokemon on each of them, one of which is basically Water Zubat/Golbat.
>the hate for Sinnoh's cavesI don't know about this one.
>the hate for the Samurott lineThey expected another otter and got a samurai sea lion.
