It's a rip-off. The idea may be original, but they stole some stuff from other games. First off, Axes: If you throw an axe into the fountain, some guy comes up, asks you a question, and gives you either a silver axe or a golden axe. In the first four .hack games, you throw a weapon into a spring. some guy comes up, asks you a question, and either upgrades your weapon, or gives you A SILVER AXE OR GOLDEN AXE. Heres a spoof of the .hack weapon spring for reference. This is more understandable then the .hack one, but then, when you get an emotion, if you have 4 or more, you get asked "You can only learn 4 emotions at a time. Would you like to replace this with another?". In the pokemon games, when you learn a new move, it asks you "You can only learn 4 moves at a time. Would you like to replace this with another?". Coincidence? I think not.
Pokemon AND .hack both came out before this game. Somehow, this game is so fun i love it but i hate it for the ripoffs.
BTW: Pokemon isn't so much as one.

I wasn't aware there was a fountain at all... this is the DS game you're talking about, right? And four things is just standard, it's much easier to have only four options when the screen is so small... hmm... I wouldn't go so far as to say it's a rip-off.
I could argue this all day. But I do see your points.

If only you played .hack. Even the axe part is the same.
PS: The fountain is obtained after a certain amount of donation to the town. I couldn't argue all day. Theres no point to arguing.
