Recently, I got three 3DS games:
1) Kingdom Hearts Dream Drop Distance: Despite Square continuing to give there worst names to their 3DS games, it's this one isn't to bad. Not the name... I mean the game... yeah, you guys get it! All joking aside, this is a pretty decent game and actually does a lot of things to try and seperate itself from other spin-off games in the series. The story isn't as confusing (at least until the end) and the new additions like cool down systems for special moves and creating/taking care of/training Dream Eaters is actually pretty enjoyable. Overal, I would say don't be afraid to give this game a chance. There is a demo on the eShop, but it's not a very good demo (at least I don't think it's very good), plus the game is only 30 bucks now at Amazon and Gamestop, so it's not a bad price right now. Plus with the huge lack of RPG's on the system right now (the only ones being this, Devil Survivor Overclocked, Tales, and Denpamen), it's actually not a bad choice to hold you over for Mario: Sticker Star or Bravely Default or Fire Emblem come out!
2) I got Cave Story and Mighty Switch Force today off the eShop! Played about 4 hours of Cave Story and I have no idea why I have waited so long to play this game. It is a fantastic game and perfect to hold of my Metroid cravings I have been having right now. I still feel it's to early to say whether the game is good or great yet, but I am enjoy it none the less. I am stuck in the laybrith right now (the one you and Curly get sent to after collecting the dogs and going into the warhouse), but I am sure it won't be that hard to get out. I really want to put more time into it, but stupid school always has a funny way of getting in the way -_-! As for MSF... it's still downloading, so I can't play it right this second, but I am sure that one will be fun as well
