Since we don't track XP, only milestones notable enough to cause a level up are noted.Other question, are milestones always level ups or are they ever just XP awards that might not be enough to level?
I generally don't care to track XP granularly, so I'm in the 1983 camp. It's fun for a CRPG to watch the bar fill up, but not worth the math and leads to XP farming at the table.
Ironically, when I've noodled about alternatives to XP ... I tend to think I'd go with the other thing from videogames ... achievements. There'd be plot achievements (find the macguffin, talk to vital NPC, discover villain's plot, etc.), player-driven achievements (craft a magic item, find lost family), and fun, whacky achievements (roll three Nat 1s in a single combat, roll a nat 20 on a superfluous check, kill a monster with an improvised weapon, score a critical hit on a foe with less than 3 HP, etc). Then it'd be a simple, you level when you have X Achievements. Some would be public, others private. It'd be more work, but possibly more fun than just math.
