Hey,
It's interesting how nintendo changes products and games from region to region. The USA version of the E-reader has a passthru/linkport while the Japanese version doesn't. Metroid Prime (European version) will be decidedly more difficult than the US and Japanese versions. The Q was released only in Japan/Asia. I know Nintendo has released and not released things in certain regions in the past (Japan-only 64dd, Super Gameboy 2(?)--had a linkport), but have they ever changed the software as to give a different (even if only slightly different) gameplaying experience? Personally, I think it's great that they would continue to work on a game even after it's been released (at least in one part of the world). I know companies tend to use the first market release to gauge interest or sales of a game, but I've never heard of a game being tweaked like Metroid Prime. I think some Dreamcast games that were ported to the newer systems might have had some improvements, but more in the technical area than in gameplay. Oh, Resident Evil on GCN had great technical improvements as well, but only a few minor tweaks. And, obviously, these were games that changed systems years after their initial release.
I hope Nintendo continues this trend. Or do some of you feel cheated that we didn't get the better Prime?
