Luigi's Mansion: Dark Moon comes out on March 24 in North America. In Dark Moon, it is seemingly the whole damn multiplayer.

You could play without the host system, but you could only play as one character. Other 3DS games have done similar things, most notably Super Street Fighter IV 3D Edition, but unlike Luigi's Mansion, that Download Play mode was heavily hampered. It also doesn't hurt that the multiplayer is a delightful competitive and cooperative experience. While we couldn't test to see if there were any limitations to the online (we weren't in a WiFi-enabled area), the fact that Download Play houses, more or less, the full local and online multiplayer is fantastic. I tried out four-player Download Play at my local StreetPass group's most recent meet-up (StreetPass Princeton represent!), and I discovered that, once you download the game from the host system, you can play the game locally and online without the host. I finally spent some serious time with Luigi's Mansion: Dark Moon's multiplayer last weekend after being very curious about it.
