It's rehash, it's Namco putting out yet another collection of Arcade favorites but it concentrates on some weird offshoot games as the 'remixes'. Didn't find a ton there that interesting, the main and center courts are interesting but don't make a ton of sense why you want to snag all the dots?
Now the Arcade zone inside does have a ton of good stuff including Galaxians, Galaga, Xevious, Dig Dug II and more classics I love so I tend to spend more time there than anywhere else. And these are original code, modifiable for your TV to fit and look great on the Wii considering their original resolutions!
Some of these aren't in the other Namco collections too, so it's a nice set in one place. I've played the collections on the 360 as well, don't see a problem with the Wii version other than the sometimes-confusing multiple controllers you can use with it.
