Maybe as Nintendo fans its up to us to BUY whatever hardcore 3rd party games we can while rejecting their softcore offerings. Even if the hardcore games suck, maybe we still need to buy them in order to stimulate new and better ones to be published.
Supporting games that suck will just encourage the development of sucky games. The third parties will interpret sales trends into whatever requires the least effort. If you buy lousy hardcore games they'll interpret it as "hey we can just release crap and they'll buy it." That's the whole problem with the Wii period. Non-games sell and third parties interpret "non-game" to mean "shovelware" and act accordingly.
Support good games. Don't settle for games that you don't think are that hot. Don't buy a lousy game because you're desperate to play something. Go hungry before eating sh!t. I hear people talk about how such-and-such a game is not THAT bad and has an okay concept in theory and if you ignore these bugs it's alright... I can't stand that. A game doesn't deserve your purchase just because it's almost competent.
It is very unfortunate, but I think the big shots who decide what gets funded and published don't actually play the games or understand the concept of quality. They understand what the game is about and the genre of it, but I don't think they are aware of how fun it is. If a shoddy hardcore game which happens to be a great concept flops on the Wii then they interpret it as that genre being unsellable on that system, and they will refuse to fund future projects down the line.
Do you remember Red Steel? It was a great idea for a game and would have been great if it had been completed properly, but the publisher rushed it out so that it would be available during the Wii's launch. As it turns out, due to the drought of such games at launch, Red Steel did extremely well, even though it was a shoddy rush job. I know it sucks if you were one of those who bought it at full price, but the good thing about that is now we have Red Steel 2 in production, and this time the company promised it will be done better and done right.
But if Red Steel one had flopped, you can be sure we wouldn't be getting a more polished sequel later on. I know thats unfortunate, and I know it shouldn't be that way, but that is how it is. Sometimes you have to get your hands dirty in manure so that you can grow great roses, you know?
