I adore Gunblade NY/LA Machineguns. I bought that game brand new before I even had a Wii, because I used to play them at a pizzeria, and they're like Virtua Cop on steroids. My favorite weird games on the Wii that people don't talk about are: Ghost Squad Lost in Shadow Rooms: The Main Building Domino Rally There are more, but those are great... if I can be bothered to stop playing Fortune Street.
One of my favourite hidden gems for the wii is zack and wiki. Has appeared in a few lists but i feel that people have forgotten all about it these days. Is a shame too as it is one of the most unique games out there.
Overturn is my top pick for Wii games no one really played. It's pretty feature rich and fun and was a cheap WiiWare purchase. I think no other WiiWare game came even close to being as good as Overturn.
Solid list, I’ll have to check these out as I recently setup and modded my original Wii. Honestly there are some great titles on Wii if people settle down and just enjoy themselves. I was playing Red Steel 2 the other day and was kind of blown away at how good it looks. I also recently picked up Excitebots Trick racing which may have flown under the radar. It’s a seriously good game, very weird and “feels” very fast. It’s just a blast to play.
