Pokémon X and Pokémon Y

Were the Sinnoh games so bad that you forced yourself to forget about them?

No. Because they brought some significant changes to pokemon, when Heart Gold/Soul silver really didn't change anything up.

Sinnoh games -
Most importantly, separated pokemon moves into special./physical on a move by move basis, rather than by type as in all previous games.
106 new pokemon.
Online battling (And trading I guess, but I never used that).
Being able to double battle team up with a npc (I think this was new in D/P anyway, correct me if it was in a gba game).
And then platinum made large improvements to the battle frontier (Which was then copy pasted into HG/SS)


HG/SS added... you getting a pokemon to follow you? Yeah. I didn't care at all about that. And I can't think of anything else that HG/SS did to change the way pokemon was played, or distinguish itself from the other games. Oh, it had two fairly barren regions instead of one meaty one, I guess, that's "different".
Plus they still didn't fix that HG/SSs wild pokemon STILL ended at about level 40~50. Which was fucking retarded when you're supposed to somehow get from 60ish when you beat the last gym leader in (The most barebones region ever, remake kanto) to 80 to battle red.
