Wiiware was pretty OK until I hit the storage limit. After that it just became tedious. I continued buying and playing games, trying desperately not to let the shitty UI and design decisions get in the way of my enjoyment, but in the end I just said fuck it. Haven't opened the Wii shop for ages. Nintendo really fucked that stuff up. Oh well, it's their own damn fault. No moneys from me, idiots.
OK, so the Wii shop firmware shenaningans played a part too. Once you go usbloader you can't really go back.
<rant>I will never understand why console manufacturers want to lock out people from their shops that refuse to upgrade the consoles' firmware. Unless there's a security risk with the shop binaries itself they really shouldn't. I mean, what's the point.</rant>
