They are releasing active cards as "characters" but those aren't characters. No real or substantial content in months. Everyone wanted Jiro and Toga, but they aren't even in progress to work on them. They release small items for real money ($25-$30) and what you get for it is quite literally garbage. Until they fix their stuff, it's not worth joining the game now. Wait until they wake up and add something meaningful to the game. The devs seem to have given up.
