Nine games have been made available from launch, with Final Fantasy Crystal Chronicles: My Life as a King being the big draw of the bunch.
Surprisingly, Nintendo’s recently announced “Pay and Play” service is supported by some of these new games (including Final Fantasy). It remains to be seen how this service will manifest itself, but it would be reasonable to expect some kind of downloadable content such as new characters or items.
The prickly issue of internal memory is likely to be brought to the forefront yet again; if you were to download all nine WiiWare games it would fill 1703 blocks of your Wii’s internal storage, and with around 1840 blocks of memory to play with in total, that doesn’t leave much space for anything else!
The rather excellent Nintendo World Report has the complete lowdown on this momentous event.
