Retail:
Rayman Raving Rabbids (garbage)
Zack & Wiki (pretty good)
Sonic and the Secret Rings (good fun so far)
Blastworks (bad campaign, good moddability and excellent content sharing system)
Wiiware:
Lost Winds (decent but way too short)
Toki Tori (most awesome!)
FFtl;dr (pretty repetitive but good)
Er, yeah, I don't have many. I'm a bargain bin hunter and there are very, VERY few bargain bin games on the Wii that are worth even their reduced price.
Hey, let's talk about a different problem: The Wii's lack of good bargain bin titles. Other consoles (except the DS) have bargain serieses like Player's Choice, Platinum and whatever else, the Wii has nothing. Nintendo even stated they don't plan on doing price drops so more people pay full price. The only price drops I see is when a game fails to meet expectations and the stores lower prices by themselves. Sure, gives more high price sales but anyone who's unwilling to pay that much will see a distorted image of the system's library, going for bargains means you end up with mostly bad games as the good ones remain full price indefinitely. It also causes purchase deadlock for me, the condition of waiting for the price drop on something, seeing the next big thing, dropping interest on the old thing for the new thing, waiting for a price reduction, repeat. The result is that I don't buy anything because I'm always given a reason to not buy anything yet.
While the same thing happens on the DS third parties have introduced their own bargain bin collections (THQ will price anything at 20€ after a while, as does Ubisoft) which often include a number of good games. Also full price is a bit lower for DS games than Wii games.
