Welcome to Gaia! ::

It's a fun card game that places you as one of five different charcters that must reach, and qualify for, the "Five Colors Tournament".
You have to play all five story paths to even play the tournament though.
And it's a fun way to learn the cardgame too.

You aren't required to fight every character that's just standing around.
Usually by the time you reach the final test, you have all the required reputation points, unless you want better cards.

The replay value in my opinion anyway is pretty good.
But the extras aren't all that usable, especially sence you have to finish the game to get the really good ones.

There is a PVP mode and an online thing that I didn't check out.

But over all it's a good game to play if you want something that's short enough to play whenever, but good enough to keep you entertained.
Unless you don't like card battle games.
