Out of the Pokémon games that most people usually consider the best (Emerald, Platinum, HGSS, BW2) which game has the fewest flaws, in your opinion? Here's my list of what I consider flaws in these games:

Emerald
>You cannot rematch Steven Stone. Once you defeat him it's over
>There's no improved rematches in the Pokemon League
>No good way to level up your Pokémon
>When the Rooftop Sale happens is completely random

Platinum
>You can't remove those annoying boulders from your Secret Base in single player mode
>Amity Square is cute, but it just feels like a test ground for the following Pokémon feature in HGSS. It makes Platinum feel inferior to HGSS in this regard

HGSS
>There's no room customization, something that GSC introduced
>some locations in Kanto were restored to their full size compared to GSC, but some others like Mt. Moon weren't

BW2
>No Original Dragon
>Route 10 and Challenger's Cave were removed for some reason
>You cannot battle against Hilbert/Hilda (it would've been cool and it would've mirrored the battle vs Red in GSC/HGSS)
>Badge Polishing was removed
>You can only battle N once per season

These are the problems/flaws that I see with these games. What problems do you have with these 4 games? Which ones has the fewest flaws in your opinion?
