I own a minecraft server, and I like playing on survival. Everyone knows I have been playing a while so they always try to kill me. Obviously I could ban these people, but I want to know if there is a way to change the gamerule keepInventory for only myself. It's a bukkit server, and I can implement plugins.
If it's a bukkit server, you could get multiverse inventories and only enable it for you. Other than that there isn't really a "single player" gamerule.
