The problem with test games is that they really weren't games that would appeal to any sort of market.
I liked Zack & Wiki, but even if that were perfectly replicatable on the PS360, who's the audience it sells to? And to what extent would those numbers be greater than on the Wii, if at all?
The most egregious example of test games is from Capcom. RE4 Wii sells one million, so they make Umbrella Chronicles, a game no one asked for ever. It sells one million somehow. So they make Darkside Chronicles and it bombs and Capcom decides the Wii audience must not really want Resident Evil.
To a large extent, people are stupid. But I think they know when they are being shortchanged on a product.
I agree.
Let me add my two cents: if last gen (Wii-PS360) taught us something is that TP developers are good at creating their own traditional games (in terms of structure, gameplay, visual and promotion).
On the other side Nintendo proposed something different from what we saw in the market with both their new concepts (the "Wii-like) and their traditional concepts (as Mario or DK) because their traditional games are, today, so rare that also if they are classic they seem "new" (I mean: different). And they were so able in marketing their products that I think that they were the best selling software house of them all.
The result was that there was a huge market that TP weren't able to understand at all. They demostrate to be able to follow their traditional more comfortable path, while Nintendo was following their own. Two different paths, imho.
TP tried to "test" that market with products that were aimed at no one, I think, unable to propose a game experience really interesting for some demographic. Zack & Wiki for example was a shot in the dark, being a genre absolutely not popular (very small niche on home console I think) with a childish look but an hardcore level of difficulty. Who in the blue hell should have bought that game? I don't know.
The only softco able to target a right demographic was Ubisoft with Just Dance and Rabbids, and partially (too late?) Activision with Skylander (still in most of the PAL charts, with the Wii version) and Guitar Hero at the beginning.
What I mean is: TP demostrated that they are not so able to think outisde the box following totally different "Nintendo" path to aim at the right market, while they were great in aiming at the more traditional demographic. This was also Nintendo fault that totally ignored by their side that part of the market, not leading TP into the construction of this "modern-traditional" (core?) segment.
So, I think that IF Nintendo is really interested in gaining TP support must absolutely offer more chance to let them being profitable with their own CLASSIC (core?) productions (action games? fps games? adventure games? core games? call them as you prefer), and not forcing them (or offering them the excuse) to think in a different way. This will also allow TP in not missing completly the "Wii U train" (if it will become a train or have some success) as they did with the Wii (and I think that despite the refuse of developing for the Wii they showed during all the last gen, I don't think that they are happy to have missed it)
Otherwise they'll try "test games" that nobody really wants (minus rare exceptions I already stated) that will fail and it will be the Wii all over again.
How should they (Nintendo) do this? I don't know. Probably proposing also IP focused to that target and PROMOTING them? Maybe. Scary fact: they did nothing about this point in the last 2 E3...
How should they (TP) do this? I don't know. Probably putting their efforts on the console as they did with PS360 at the beginning (without any real fact that assured them to be successfull, but forcing themselves this success) without "testing" with poor B-team and shovelware titles...
