I got mixed up, +a was just for the first EX game. There was an EX2+ on arcade and also EX2+ on console but the console version had Hayate. Evil Ryu and Gouki were in EX+a, but in EX2, Gouki was dead. EX3 cleared away a few things.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
