Super Smash Bros. for Wii U - This game is just incredible, and I can't believe how many hours I put into it. Pitting video game mascots against each other has never been more fun. (except maybe in MUGEN)
Freedom Planet - It's like Sonic, but not! Also, incredibly difficult and with really good voice acting! Music's nice too, but the voice acting stands out the most. It's on steam!
Puyo Puyo Fever 2 - I certainly didn't expect to see this in the bookstore, but I bought and now it's mine and it's the best and I still don't know any Japanese so I don't know the plotline of this game. Yep.
On a side note, Shinomi-chan, you still haven't finished up NiGHTS? It's easy! You just walk into the pagoda thing, and ignore the fact that all your star orb things just got stolen, and as NiGHTS get them back by going through rings and collecting blue orbs. Once you collect the orbs just ram into the big giant demonic machine (called an Ideya Capture), and if you have enough orbs you will break it and get the Ideya inside. Then you go to the pagoda after you go around once (I think) and it will take you to course 2. Repeat that thing again and you will eventually finish the 4th course part, after which you fight the boss in a certain time limit. After this, you get a grade and if you get all above C on your courses you unlock Twin Seeds! Sorry for going on a tangent there. Did you catch all that?
