Official Nintendo Magazine gave this 90%, but what does one expect, they're official! What a joke. As much as i like the mario games, Mario All-Stars Wii isn't worth the asking price, nor the 90% mark a magazine like ONM gave it.
Let's face it, it's just a lazy port from Nintendo as it's just a SNES rom bundled with an emulator on a disc, around 8mb, if that. The interface within the game still shows the SNES controller, Nintendo didn't even bother to implement a proper Wii interface within the game.
Nintendo could've went into overdrive with this bundle by updating the graphics to NSMB (New Super Mario Bros) standard, adding additional games i.e. Super Mario World, Mario 64, etc, and by implementing a proper 16:9 widescreen support for all games. But they haven't.
What we have is a cheap as chips cash-in wrapped in fancy packaging. Buying it would send out all the wrong signals. Plus the PAL version is only 50Hz, yes, that means 17% slower than the US/JPN versions, which is shocking for any title in 2010.
Avoid at all costs.
