Genre: Super-dimensional Football RPG
Developer: Level 5
Publisher: Nintendo
From the humble beginnings of a dinky little after school club, it has been 7 years since Mark Evans led Inazuma International to victory in the Football Frontier International. The impact of Inazuma International's victory was so great around the world, football had turned into an activity of high prestige, almost fanatical and religious, and so Fifth Sector was born. Under the leadership of "Alex Zebal" (Really? THAT'S what the dub team came up with?), Fifth Sector controls football by giving every single team a balanced amount of wins and losses akin to a Totalitarian regime. Arion Sherwind has been accepted into the prestigious Raimon Jr. High with hopes of joining the great football club that Mark Evans had revived, completely oblivious to the existence of Fifth Sector.
New Gameplay Mechanics
Spirits
They're probably what you think they are. They're spirits summoned by characters to power up themselves. These spirits are actual physical manifestations of energy so that they visible to everybody unlike in previous games where spirits appear due techs. Such as how nobody actually sees Axel Blaze's fire demon during Fireball Storm.
Special Stadiums
Different stadiums will now have different effects. Some examples: one stadium will have a tornado, one stadium will have a pitch made of ice, or one will have a pinball theme with flippers and rebounding targets.
Version Differences
Mark's Wife: In Light, Mark is married to Nelly/best waifu. In Shadow, Mark is married to Camellia/fake/red herring.
Teams: In Light, players can fight Unlimited Shining and Southern Claw. In Shadow, players can fight Ancient Dark and Northern Fang.
Other differences including version-exclusive Spirits and Techs, but there quite a few of them to list.
