Milestones based on how far other players get would be great for this. I had a decent time playing when my goal was to reach wave 17, which another commenter said they reached. The game could list four milestones: the highest wave ever reached by other players, the median wave reached, and the 75% and 25% quartiles. So the goals for expert mode might be wave 5, wave 14, wave 21, wave 53 (making those numbers up). And those numbers would change as more people play the game.
