Digital Foundry - Luigi's Mansion 3DS analysis
What made Luigi's Mansion so special when it launched with GameCube and how much of the magic persists into the new 3DS version? This video details the history of the game, and has all the graphics comparisons and performance analysis you need. It's a really decent mobile version of a classic Nintendo title.
Grezzo has done a tremendous job in adapting the game to Nintendo's aging portable system and in the end, has produced one of the best-looking games on the system. The controls are also well implemented. If you're playing on a New 3DS, you get to use the nub just like the right stick on GameCube but this time, it can actually be inverted. You can also use the gyro feature to aim your vacuum up and down across all versions of 3DS hardware.
