I think the e-Reader has not been used very well to enhance GameCube titles. To me, it is clearly best suited for Pokemon, so you can combine the card game and the video game. Why isn't there a Pokemon Card Game simulation for GBA that lets you scan in your real Pokemon TCG cards and thus obtain them in the game? Well, one obvious reason is that the e-Reader has no cartridge pass-through, which was a huge design oversight that has ultimately limited the device to the most basic gimmick functions. The basic concept of implementing a cheap data storage option, especially on trading cards, is a fine and novel idea. Unfortunately, Nintendo has yet to develop the hardware to make it really useful. I think a lot of us would like to see a small unit that would let you create your own e-cards, as well.
