We'll agree to disagree. Wii got fed crumbs from Capcom's table. RE4 while good, was a port. The 2 rail shooters were thrown out to Cavia, not mainline developed nor mainline games. MH came because of financial constraints. Not sure MH is their biggest franchise. Japan yes but not elsewhere.
Look at this list of franchises, some with multiple entries. Did we get any of these? Devil May Cry, Lost Planet, Bionic Commando, Marvel vs. Capcom, Dead Rising, Street Fighter, Resident Evil(main series). No we didn't.
