The #TorontOSR posse met up recently and Paul ran a game of D&D for us using his tweaks and house rules. When I run games, I have players re-roll their hit points at the start of each session. This is something I picked up from Brendan. This mitigates how overly impactful a poor dice roll when rolling your hit points can be. Paul takes this idea further, with a scheme that reminds me of the hit dice mechanics from Carcosa, but a little less bananas.
