good ideas, the capturing idea im guessing came from FFX, sounds good, but with capturing, u urself will have to capture it before u can battle it out, otherwhys u can just keep fighting till someone brings one in, then u would be able to fight that without actually having to have adventured anywhere, and it would be nice to have a team battle in the arena where a party can kill 1 special monster that can only be found in the arena and has to be unlocked by maybe a certain number of monsters captured by u, or certain number of quests, something unique so that a rare drop can be made that will drop something very good (very strong armor with a beneficial spell, or the same with a weapon, or maybe a special item that will allow for a certain thing to happend, such as an epic quest or such)
