This is a a great game overall you dont need to pay 100$ for good fighters it only cost 1000 chrono crystals (which they are easy to get) and that gets you a guaranteed sparking fighter which is the best you can get. I havent payed a penny and i got 4 sparking fighters goku, super gogeta,super, and fully powered super saiyen goku and i started playing a week ago.and the game mechanics are so good it's very simple and easy to learn and once you've got good Fighters it's easy to pass the campaign.
