Impossible Sparring Challenges
The purpose of career mode is to create and level up a fighter. The most efficient way to do this is to complete sparring challenges. A lot of the challenges are special moves of other characters. This forces (encourages) you to learn moves from other fighters.
Not every move on the move challenge list is accessible to every fighter. If you are playing a female fighter you don’t have access to any of the male fighters to learn their moves. I seem to remember this being an issue with 4 as well. This makes completing some challenges impossible.
If we could chose the challenges we want during training this wouldn’t be an issue. It would allow you to focus on leveling up the moves that you want your character to focus on. I really regret purchasing this game.
