Terra Force, in its second version set, presents a different iteration of the arcade game. Its imperfect graphics, similar to set 1 of the Japanese release, suggest either a common issue in the game's development or a deliberate stylistic choice.  The 'Edition' tag may refer to a specific release or revision, but the lack of detailed documentation prevents further elucidation on its specific differences from the first set.
