I must note that the Wii's line-up is not actually legitimetely bad. It is only truly bad if you are someone who considers anything that scored less than a 9.0 "bad." Even then, I would only consider that criteria valid for the Wii's "hardcore games" that were hyped and subsequently flopped like the Conduit, No More Heroes (?), and Madworld only because the experience they provide is somewhat common on the other systems.
The REAL problem with the Wii's good lineup finds it difficult to find support from the vast majority of the consumer base regardless of how good it actually is. The blame goes both ways; it should be blatently obvious to the developers of these rather unorthodox games that first and foremost that you need to come up with an idea for a game that will actually appeal to the consumer base before you start to build an excellent game. This is where the problem lies with games like Boom Blox, Excitebots, Little King's Story, Rune Factory, Zack and Wiki, and others like them, they are all not only superior games to the overhyped hardcore games, but they are also some of the better games for their particular genre. Their problem is they don't appeal to the general consumer or even reach out to the consumer base by way of advertising, casual or hardcore, and basically only have niche appeal regardless if they are all potentially part of the top 30 games on the Wii.
This also goes to the consumer base as well since many casuals don't even by games, let alone these games which aren't even heard of by enthusiastic Wii owners, let alone them. And the hardcore are only looking for familiar series or very hyped hardcore games and when those hardcore games flop, they consider the Wii's lineup horrible. I personally do not mind them not giving these games a chance since they do have the right to not play them though not factoring them into the Wii's lineup at all actually irritates me as people who call the lineup bad, but not know about most of it are just being ignorant (not accusing anyone on this board of that ignorance).
Sadly, the Wii needs major third party franchises to grace it before it is actually given any credit. I do agree with Anthony on one thing in that the entire generation has been similarly lackluster/good in terms of software quality. The PS360 combo only obliterates the Wii in terms of power, major 3rd party support, and online. I personally beleive none of them have any right to brag about excellent software superioirty over the other two, quality wise.
Why don't you play a Wii game that doesn't force you to use motion controls? There are plenty of them enough of them five that aren't found on other systems that are played with almost no dependence of motion.
