You don't kill a genre by under-representing it. Markets don't work that way. The basic mechanism is thus: suppliers provide a product to the market, which is consumed by interested parties, creating demand. Based upon the demand, suppliers adjust their supply and their production values. The failure of games like No More Heroes and Zack & Wiki to have significant market impact is a simple case of the demographic at large being disinterested combined with a lack of appropriate advertising to the appropriate demographics that would want them. The best way to get more attention for such games (and thus more sales) would be to give them advertisements on a medium besides the internet or gaming magazines.
Sky Render - Sanity is for the weak.
