European & Aisian Starters are a complete, playable set unlike the US starters which had been split in two: Red starter 1 & Blue starter 2.
One needs two US starters or one US starter and seven additonal figures (from another starter or from the 'boosters') to play the game with US sets.
This game would be extremely popular had Bandai released the European version in the US rather than getting lost in odd marketing tactics.
