Here’s a fun suggestion, how about you unlock the desired players by playing the game? Could even put it into an immersive context, you beat brazil and subsequently unlock their players for your team.
What’s so fun about buying a chance to get your player? Is it possibly the shiny colors and the happy soundeffects that are specifically designed to make your brain addicted?
Which version of FF7 are you referring to? And also which version of Link?
Either way, probably depends on who the writers want to win lol.
