Things David misses about old D&D:
2) Seven-hour combat (5 seconds of rolling dice, the rest spending arguing about the rules).
3) Vecna showing up randomly to wipe out party members.
4) Yelling, "ROLL INITIATIVE, M*THER F*CKER!," every time a party member pointed out a technical error on his part. This leads to the the next point:
5) Rule Zero. Oh, How David misses being able to claim almighty DM status on a whim. Get a lucky critical on that wizard? Oh. Sorry. That was just a clone, the real one is behind you. Did you survive the trap? No worries, the mountain blowing up with you in it. You know. Slight changes.
