FE on GBA is my fave FE that released in America. The second one, not so much, but this has nothing to do with aging, it never was very good for an FE. I love all FE games, to me it's just a matter of if they get an 8, 9, or 10 :) I find every game in the series to be pretty playable, regardless of age, and there are remakes to make the older ones even more so. I'm really not sure what part of the games would even be considered to have not aged well.
The only problem I have with 7/8 is I don't find a challenge... In any of them. Even if it's something as silly as saving all the NPC's, I'm still able to blitz every chapter w/o deaths. It's just gotten too easy with consecutive play.
I am currently playing FE 7 on the way to 6. I'm playing them in chronological order at least until awakening this monday. I don't expect to be finished with either one by then, but.. * shrugs * I'm still enjoying them. I do miss the tweaks and flash that FE:A will deliver, but I embrace them as they are. --- "The wages of sin is death... but the hours are good." ---Psycrow, Earthworm Jim cartoon
