It's a pretty cool concept, the characters or "Dino Robots" are based on Zoids where you build them first in the form of a Model Kit where you combine parts, then after that you can interact with the chosen character in what I'd like to call their testing zones.

First of all, the animation for each characters is well-done and not laggy, as a kid playing this you really have a sense of power when controlling your chosen robot.
Secondly, the battle scenes are based on those rock, paper, scissors games like Dinosaur King, you either pick the right symbol or the opponent attacks your robot and damages it, it's pretty easy to see the opponents pattern, so don't worry if you made some mistakes.
