It would be quite cringe of me to not make at least one blogpost this year, so here it is. Skip down past the images for the AD&D discussion.
I'm currently playing in a 1.5+ year-old, rotating DM (not by design) OSE campaign. It's fun, but I've noticed that whenever I DM sessions the players are as paranoid as level 1s despite being the majority of the party being level 7-9 and having access to Raise Dead from two PC clerics. While I've been known to throw some meta-fucking curveballs (a lich that was a pseudo-lich; a white dragon that was an albino red dragon), the group sometimes looks for twists were there are none: Perhaps I'm too good at being unexpected.
In real life, I had an opportunity to run a DCC funnel for two MTG friends, and now sure that I have at least one potential player, I've been contemplating setting up a real life OSR table. My brain says OSE Advanced but my heart says AD&D 1e. We shall see.
Excerpted and slightly edited from the 1e DMG (Premium Edition), p. 13 & 15
Wish, the ur-spell of AD&D, ages the caster 3 years per cast. Humans can die as early as age 62, and the starting age for Human Magic-Users is 26-40. 12 Wishes (or Golems to put it in perspective), places the 26-year old human m-u in the "death by old age" zone. Meanwhile, Elf Magic-Users with 18 Int are limited to level 11, barring some of the Dragon Magazine and/or Unearthed Arcana additions (which are not universally accepted despite how kickass an elf ranger/druid/magic-user sounds). As an aside this also resolves the "why don't clerics just revive everybody?" question: A powerful mortal servant of a god shaving 3 years off his lifespan to cast a spell that requires a system shock roll is reserved for heroes (as seen in the 1e Dragon Magazine write-up of Wee Jas).
How then, do human magic-users get around such a huge hurdle? The simplest way is to either never cast Wish or save it for emergencies. Potions of Longevity can stretch your life, but a cumulative 1% chance per potion drunk to immediately re-age is very risky. Direct divine intervention is possible but hard to get. Ultimately the best two options are lichdom or forcing monsters and items to do the work for you.
Lichdom technically removes the downside of aging, although I would argue that the skeletal/decaying form of the Lich and later Demilich actually betrays that it does take a toll on the undead body. It's easy to see a "fresh" Lich being relatively corpse-like but not rotting until the pedal hits the floor and 10, 50, 100 Wishes put the stress of 30, 150, 300 years on the body. Maybe ol' Acererak got cozy in his Tomb of Horrors and then spammed so many Wishes that the weight of 3000+ years turned his body to dust except his skull.
The other way is by hunting down magic items, sites, substances, and artifacts that can grant Wishes, or enslaving, tricking, or forcing creatures that grant Wishes to give them to you. That means a lot of traffic with demons and devils, particularly their higher-ups. This opens up a whole other can of worms, as there's definitely an indistinct but existent line where continued dealings with Evil spirits is definitely not morally Neutral and is clearly Evil, which may draw the attention of Good to an overly ambitious magic-user.
But what does this matter for THE GAME? Well, if you establish patterns early on, you show players how they can use those patterns, in addition to creating logic for dungeons. Dozens of Golems in a dungeon means Lich or Extraplanar, likely Evil involvement somewhere, which will be borne out by more Undead or Extraplanars, respectively. It also makes things like methods of golem construction without Wish use (as it was OD&D via The Strategic Review) both a hook and something valuable in its own right.
