Nintendo DS VS GBA
I wrote this post draft years ago, at a time when I had only recently switched to Nintendo DS after years of loyal GBA playing, and I honestly thought the former console had some major benefits over the latter.
It does, but the benefits are slim compared to the cons, and as the benefits of the original GBA don't all carry on to the modified form of the GBA SP - there really isn't much you can do with a GBA that you wouldn't be able to do better with a DS. Only if you don't compare the actual games, the GBA may pose a serious challenge. After a few years of getting used to the NDS, and then a few days of playing some GBA once again: I feel like it's time to finally post this thing!
