I also suggest retail (I am a collector + you can use it on more than 1 3DS + you get a code to participate in the SO MANY GAMES promotion) but I got it digital with the SO MANY GAMES promotion. And because I thought this game is a nice game to play for just a few minutes each I chose it as the FREE game.
I got "6" retail games and got 2 for free. (well actually 4 for free thanks to the German Amazon promotion buy 3 pay for 2)
The other FREE game is Lego City since Nintendo games keep their value alot longer than third party games and LC being an open world game with alot of little things to do, I thought that it would be a wise decision to get it as the second free game.
Got DKCR3D, Castlevania, FireEmblem, Luigi's Mansion, MonsterHunter3 and a friend gave me his Pokemon Mystery Dungeon code.
