Dissidia Opera Omnia is a rather huge game. Consider this: there are 25 story characters. People are limited to a party of three, though they can have 10 preset parties. In addition to those characters guaranteed from the campaign, various events offer the opportunity to earn many more heroes from the Final Fantasy series for free. Only Vanille and Setzer have been added to the roster so far, but we can eventually look forward to people like Maria, Kain, Rydia, Faris, Celes, Aerith, Zack and Ramza. With such a huge cast, people may have trouble finding specific characters to use for certain needs.
