What we really need is multiplayer Air Force One, with everyone in the party having their own colour of targeting reticle. You can have some targets anyone can hit, or some targets matching a colour of party member that only they can hit. You can also have some goofy enemies, like Gold Saucer employees wearing a goobbue costume or something that take a lot of shots of take down.

Of course, this is a layer of infrastructure not programmed into the game right now, since it leverages a lot of the activity client-side so that it feels responsive. Perhaps someday.
