Lesson 6: not made by EA. :)

It's not like this never happened before.

Protip: Always ignore the 800-pound Gorilla in the room. It makes analysis of the game industry so so much easier

 While the Wii's track record to sequels is a bit iffy at times, I think the inevitable successor to this will be fine - as chances are it won't so much be an 'Epic Mickey 2' as it will be an 'Epic Donald Duck' or something that has enough to distinguish itself and entice Wii buyers to not think it's just more of the same.

The title of the successor will be More Epic Donald and it will sell more than 5 million copies.

All the publishers have ported lots of games to the Wii already, so why not these ones? There has to be a reason other then an attempt to 'lock out' the Wii as well, they've all ported games to the thing before, not every publisher would do it and they all make exclusives for the console. 

 I don't think either of us know enough about game developement to really say what can and cant be done easily - however all articles I've found regarding this of thing point towards my idea that doing a PSP game alone is simply cheaper and faster. The two linked below both have PSP developement cited as much cheaper then Wii developement, which could easily explain why these games (Which would off of sales date both be poised to sell roughly the same on Wii and PSP) are only financially viable on the cheaper costing PSP.

 It also destroys this idea that a PSP game simply be ported to the Wii for no cost, as well otherwise the Wii dev costs would be equal to that of the PSP as people would just make a Wii game for the PSP and then port it :P.

 The only example i can remember of a PSP game being ported to the Wii was that MEdal of Honour: Heroes 2 game. It had an extra game mode or something, but the port still took EA 4 months from announcement to come out, hardly an insignificient investment of time and money.

I'm under the impression that, often times, whenever the Wii attains a title that achieves any type of success, there is always a half-assed outlier made up in an attempt to negates its authenticity.

This impression has only been enforced in this thread.

@rolstoppable but PSP has had games that have done well in that genre, the Wii not so much. So maybe the devs were foolish enough to think that they could capture that spark??? THe Wii never had that spark for those kind of games to begin with. Yes, i dont think the games should have been made, ill go so far as to say that HD games should not get ported down to Wii or PSP at all. Either they put some b team on it and it sucks(Hot pursuit) they do manage to get it to work but by that time no one will care and whoever wanted to play the game have had there fill (soul calibur broken destiny) or its just some versionthats not as good and will sell worst than the HDs anyway (spiderman, force unleashed 2, etc) UNLESS they actually do something drastically different and make it good, which is rare is the only way I can see it work (force unleashed 1 for Wii was good) and of course the more family oriented games are going to do better no matter what (Toy Story 3, even though it was missing that key toy box feature)

@noname  Mario Kart is not an arcade racer, its a kart game, even so thats still just one game, what about the others, why does Wii owners not buy those? (they probably suck)

@Degausser again you are the voice of reason and might I add that the PSP version of MOH heroes 2 still outsole the Wii version

I wasn't really suggesting that it did well (in terms of huge sales) - I was kind of suggesting that for a game to sell as The Conduit did and still get a sequel it mustn't have cost a huge amount to make (nowhere near the likes of, say, Assassins Creed, RE5 etc. - third party HD blockbusters).  In that regard, it didn't meet all the criteria set out in the OP.

I'm not sure you're using the same definiton of "arcade racer" as the rest of us.  As far as I know, you're the only person who puts them in a separate category because they're riding go-karts instead of regular cars, hovercraft, or some other racing contraption. 

As for other racing games, arcade or simluation, there have been a grand total of five others on the system, three of which I've never heard of.  And one of those five is the NASCAR racing game, which is the sixth best-selling NASCAR game of all time on any console.
