Custom Robo, you assume cool mecha fighting but not good mecha fighting.
The gameplay that Custom Robo brings forth is rather dismal offering little to no adventure. The entire world is layed out so that navigation is easily followed enough so that younger children could easily walk from place to place, but making the game seem absolutely annoying leaving no room for exploration as you are confined to a track from location to location. Where you will be riddled with annoying cut scenes leaving the action far in the dust.
Each battle is fun and remotely new, giving you the customization options to change each weapon you wish to take into battle and even allowing you to change the model of the robot you fight with. There isn't all that much music in the game soundtrack.
Overall, Do not purchase this game it isn't worth spending your money. What is with Robot games being so hyped.. but in the end are horrible.. Look at the gundam games.. for example
