In hindsight, it was a fantastic decision on Nintendo and Game Freak's part to remake the original games for the third gen. Not only were a lot of resources in place for them already to save on time and expenses, but they were an easy sell to both new and old fans alike. Plus, it paved the way for HG/SS and OR/AS, all of which were greatly anticipated by fans.
Outside of the whole business thing though, it would've been nice to see them held off until later, with each remake being a generation or two later than they were (imagine FRLG on the DS, and then being able to explore Johto and Kanto in Gen 6). But, I think younger me would've been bored with only Hoenn, as great as Emerald was.
