New hint for 11 and 7.
11: Unlike the first game in the series, this 2nd game has turn based RPG combat much like Pokemon. Unlike Pokemon it is 3v3 combat, and lots of fusion like Persona.
Famous mascot characters include a yellow dinosaur and a blue dragon like monster. But of course you can choose between 195 monsters. You can join 1 of 3 different teams Blue Falcon, Gold Hawk, or Black Sword.
This game is part of a media franchise that used to rival Pokemon in the 90s, popularity has since waned comparatively.
7. This game introduced Dual wielding. Nothing like double Needling an enemy and then they explode. The promotional cover art often features the main character dual wielding.
