Yes, scripting is more diverse than only custom enemies and custom bosses. I'm fine with the entire list, except the part about scripting being split into just custom enemies and custom bosses. I'd suggest including item of the year too (but that'll break the limit).
I'd still prefer "Most Anticipated Quest" rather than "Project of the Year" since a highly-anticipated quest doesn't necessarily have to be part of a project.
I actually think by "project" they mean a quest that is or was in production. You anticipate quests that are yet to be done, thus they are still in production.
