Here are links to the Actual Play reports of my Adventurer Conqueror King game that I've been running for awhile now. Characters started at first and the highest anyone has made it to is 3rd so far. It's an old school sandbox style game, started with B2 and the Caves of Chaos (as you do!). I've set it in the ancient history of a campaign world I've been running for around 20 years through various versions of D&D (and other games) from 2nd ED AD&D, to 3.0 and 3.5, and now back to a B/X simulacrum.
