in ffxi there was a dynamisis instance where only 1 full group can go in at one time, all linkshells pretty much set different times from each other ...was very stupid way to do it. also a few other things were like that, like parts of passes to things and battles. it should be where anyone can do them at same time though, it created lines for these things for weeks ...and in reality when all was said and done the acual time getting like collesium passes lived out longer then the acual mini game.
