So, i do think they should let Arc the lad die. That series has dragged on since the third installment. It wasnt made to be a series.
Wild Arms is almost criminal that it hasn't seen another sequal. They should make HD ports of 4, Alter code F (remake of 1) and 5 aswell. After that deliver us 6 for the ps4.
Legend of Dragoon remake or sequal should happen aswell, and finally Rogue galaxy 2.
No need for new IP's for now. Just resurrect those 3 and build their brand.
