ClaudeLV250- Agree with everything you said
steverhcp02- Reason those mini games sell so well on Wii is because yeah they are more popular with casuals and little kids, but they are also only $20, that's what they're into, and that's what they've always been into even on the PS2, PS1 (maybe not to the same extent but still). Another thing to keep in mind too is these shovelware games that sell well also have incredibly poor satisfaction scores on amazon and best buy's websites, even though they sell customers aren't satisfied... just something to keep in mind since as a company you want to build a good reputation, not a poor one. Also casuals aren't the only people who own Wii, devs seem to overlook that EVERY TIME!
I honestly don't think studios need to be creative on the Wii platform, in fact I think they need to hold back and just focus on making a good game. Personally I think Resident Evil 4 and Pikmin NPC are the best at taking advantage of Wii's interface out of all the games that are out, ironically neither game was originally designed with Wii in mind. Difference is they made a great game first and figured out a practical way to enhance the gaming experience with the Wii's superior controls. I'm not saying this should be the method for making every game on Wii but devs really need to take a step back and ask themselves if they are trying too hard to make the gameplay on Wii more different than it should be.
Perfect example is rail shooters, I hate rail shooters and I would of bought Deadspace and the RE Chronicles games in a heartbeat if they would of been third person, but they weren't, bottom line this was a deal breaking for hundreds of thousands of Wii owners I'm guessing (just look at the massive backlash these games got when they confirmed they were rails).
Conveniently you left out the fact that RE4 is the best selling mature game on Wii and all of Nintendo's core franchises are selling better that ever. I doubt grandmas and toddlers are playing Galaxy, Metroid, and Twilight Princess. Bottom line; quality mainstream games sell.
Out of the entire collection of Wii games I own, only 2 I like haven't sold over 1 million, and those are SSX Blur and Pikmin NPC. I got Medal of Honor Heroes 2, The Conduit, and No More Heroes and can see why none were big hits, all were mediocre, average at best and that's why they give me more buyers remorse more than every Wii game I own. None of the Wii games I own that sold over 1 mil have given me buyers remorse on the other hand. Demographics isn't the problem, quality is the problem.
I'm going on way too much of a rant so I'm done.
