"Last week I suggested the Wii was headed for bumpier roads, not because the system lacks games, but because it lacks as many first tier titles as either the Xbox 360 and PlayStation 3. By "first tier," I mean stuff that's on everyone's radar before it comes out, games that make news beyond the enthusiast press, titles or franchises that sells around a million copies pretty much out the door, e.g. Halo, BioShock, Guitar Hero, Gears of War, etc. You may be really, really into Rayman Raving Rabbids or MySims or Carnival Games or Dance Dance Revolution: Hottest Party, and that's cool, but those games are small change on the sales charts."
