Valkyria Chronicles 2, a PSP game, looks to have more polish than the Conduit, HotD Overkill and Madworld combined. I'm exaggerating, of course, but the point I'm trying to make is that they take handheld development and publishing more seriously than they would on the Wii. I saw more Bayonetta commercials in one hour block than I ever seen for MadWorld.
I thought SEGA, an integrated hardware and software gaming company, would understand the Wii. Apparently I was wrong.
