I had an idea for a great PVP game. Basically you start with a prebuilt map and you pick a team. Then you fight, say 10 v 10 or so. But the way you win is destroying a set percentage of the enemy's base as well as killing them. Now here's the cool bit: the enemy base health is shown as a boss health bar at the top of the screen titled "Enemy" and your team's base's health is shown on the XP bar! Possibly titled "Team" but I dunno if that's possible. The collective health of your team's base falls as blocks are destroyed. (Maybe your particular wool color? Red team and blue team kind of thing?) Evem better, multiverse compatible so it can be run alongside a survival server. But not mandatory. Who could do that?
