Yeah, somehow, developers love to port over a crappy game to the Wii and call it a day.
But to be fair, many games on your list are not really ports:
Dead Rising: Chop Til You Drop
Kore
Baroque
Blazing Angels: Squadrons of WWII
Death Jr Root of Evil
The Godfather
Medal of Honor Heroes 2
Alien Syndrome
Far Cry Vengeance
Splinter Cell Double Agent
are not ports. Most of those games are just cross-platform or mostly having new content.
