New sealed? $25 would be the best deal I've seen all year long.
Cheapest a used copy (cart only mind you) goes for is $25, if your lucky enough to find one at that price. The game is quite possibly the rarest gba game out over in the US.
As for the game itself, it looks and plays very much like FFTA, but IMO FFTA is better. Regardless it’s a game no strategy fan should be without.
