CardMon Hero pretty much looks like your typical anime-inspired F2P MMORPG. It uses bright colors, with the inclusion of kiddie-version sprites and monsters. The game in fact reminds me of games such as FlyFF or Rose online. The game environment is pretty light and partnered with an upbeat and catchy but repetitive tune.
The game's light-hearted nature can be entertaining, especially for those who are looking for a less serious themed MMO. CardMon Hero pushes the right buttons in terms of casual entertainment while distinguishing itself with cartoony card "partners" known as "mercenaries".
