The first generation was mine, it barely seems as long ago as it was. Me and my brother got Pokemon Blue and Red respectively, and we would always play together. On days in the afternoon, new episodes of Indigo League would come on Heck, I still remember going to see Pokemon: The First Movie and getting special TCG cards for it. Those certainly were good days.
I have to say, looking back, 4Kids put a TON of work into the localization of that season. For all of the bad things you would expect them to do, they did a lot of good for the Indigo League (as well as seasons 2 and 3).
