Acquire other (more productive/creative) hobbies/activities which excite/interest you enough to channel that same energy/focus. I had this problem with EverQuest for a while, and other MMOs/Open-World games, then "virtual world" software (OpenSim/Second Life/InWorldz) that I was semi-addicted to led me to a (revived from olden days) interest in programming/scripting, and a (newly rekindled) interest in 3D modeling/graphics which at first I had learned for the sake of creating content for the virtual world and other game engines. I just used that interest in those "new" hobbies to start finding "excuses" to do more productive things and learn further skills around those interests which sucked up enough of my time and focus that the games simply no longer held the same sway that they once did over my attention. Now that I've honed those skills somewhat, I'm moving into learning the Godot game engine, in hopes of creating my own amusements and tools with those skills. :)
