nonmae- true but I think we know that mostly Wii is dominated by Nintendo's core franchises. But this is not unusual in a market for a majority of titles to dominate. Usually its well established franchises selling loads better than the rest. Well established franchises usually are a minority but always encompass a majority of sales.
Why does this happen? A few things. First, your majority buyers are mainstream buyers. Actually the funny thing is that mainstream buyers probably represent 80% of your gamers. Mainstream includes your casual gamers as some refer. The rest are your long time gamers or hobbyist. Yall call them the hardcore. Thus the mainstream buy the well established franchises and the rest buy the other good ones. NOw that doesn't mean it works exactly like that but you see the picture here.
Second, the majority of games don't get proper advertising nor are meant to gain huge sales. What we call shovelware. Sent out there to hopefully get a few thousand in sales and thats it. Sometimes games from smaller developers have similar effects like Mushroom Men. While a small percentage of games have the huge budgest and large marketing and take up the majority of sales like Need for Speed and Call of Duty.
Finally, establishing a new franchise is so difficult right now. Because the majority of your gamers are mainstream, selling a new product is almost impossible. Unless it's something like Assassin's Creed or Gears of War where it's so alike to everything else in its genre, then your not going to get anywhere. Thus these large new IPs go out and don't do to well despite have huge production value. Dead Space right now is the one that jumps out at me the most. EA has already complained about that one in similar terms.
But this is a problem in the whole industry and not just Wii, as some would like to think cough Stick. How to fix it is simply continue to make gaming more mainstream while transforming your average mainstream gamer to a hobbyist. Something Ninty has been trying since the DS.
