I was already planning on buying it, because I had assumed it'd be given the FRLGE treatment with a gross amount of extra post-game content.
I didn't even like R/S all that much, for some reason, but the gym leader rematches plus Battle Frontier were enough to persuade me. FRLG on the other hand.. if you didn't like Red or Blue you probably wouldn't get into Pokemon in the first place. My only complaint with that game was the soundtrack, which was shat on, copiously.
