(Disclaimer: I worked on the US version, so if you don't know me/trust me, feel free to disregard this post.)
For the rest of you...this is the first game of its kind (the Japanese F2P gacha kind) to really sink its hooks into me. Way more than Puzzle & Dragons ever did (which I also like, but not nearly as much as MS). I've probably played over 200 hours of the Japanese version over the past 6 months. There are two main reasons for it, I think: 1) it's an action game with simple controls (but complex physics), and 2) it's got four-player online co-op. It's a fun game to play alone, but playing with others really takes it to another level -- it's only once I started playing co-op that I started getting crazy into the game. You only use stamina if you're the host; if you run out of stamina, you can still join other players' games whenever you want, which basically means you can keep playing forever if you have friends to play with. Plus they give you Orbs (this game's currency - your Magic Stones, if you will) like it's nobody's business. The first 10 players you play co-op with, you get 5 Orbs a piece (!), and then you get another one per person for the next 90 players. Plus they give you 5 Orbs (plus some other stuff) for every new player you invite to the game who completes the Tutorial for up to 100 (I think?) players. It's kinda ridiculous.
BTW, the main game designer is
Yoshiki Okamoto (Street Fighter, Final Fight, Forgotten Worlds, Zelda: Oracles, etc. etc.).
Once it's out in the US (soon!), I definitely want to play with you guys!
