To put it bluntly, if I owned a Gameboy Advance and already played one of the Hoenn games, I would not even buy it. As much as I like Pokemon franchise (the games, at least), it's formulaic to a huge fault. Still 3 starters, grass water fire, still 8 gyms, no more no less, evil team to beat up and elite 4 and champ at the end to name a few traditions that should have been twisted about or flat out ditched long before now.
Remakes only made the issue even more in your face, and I sorely regretted taking many of my friend's advice on getting Heart Gold - they didn't even try to solve some of the issues that the original gen 2 games had such as level scaling and pokemon variety. Made me wonder why I just didn't play Crystal again.
Like I said, only reason I'm getting it is because I never played a Hoenn game, but as much as I dislike the idea of remaking games in a very formulatic series of games as it is, it's entirely possible it could cement itself as my favourite pokemon game, but that mainly boils down to how good the gen 3 games originally were unless they make fairy big changes (hopefully changes that improve them) to the games.
