Picked up and started playing LBX: Little Battlers eXperience for 3DS and got up to Episode 3.
I've never heard of the game, I just thought it looked fun, but it's actually freaking good!
The cutscenes are like an anime and the story is split up in several episodes which just enhances the anime vibe.
It might not be an incredibly hard game (the AI isn't that smart and I have been fine with just spamming my charged attack) and the story is incredibly cliché (kid gets unique robot, manages to beat everyone and saves the world helped by his friends), but it's just really fun.
Reminds me a bit of Custom Robo Arena for DS mixed with the Megaman StarForce series.
