otherwise known as Mon-Colle (モンコレ)) is an out-of-print trading card game developed by Group SNE.
Monster Collection was later expanded to a roleplaying game and was the basis for the anime series Mon Colle Knights.
The Monster Collection game universe is a world connected to six gates of fire, water, earth, wind, good, and evil, representing East, South, West, North, Heaven and Earth.
Each monster has fire, water, earth, wind, good, or evil element.
A monster's ability is decided by battle spell, unit's equipment, combat items, and terrain.
