The High Aldwin
While I am happy for you both, and, no, there doesn't have to be a "reason" (which is why I said in the OP I wasn't really expecting "answers" to this...), the post by James in the OP really got me thinking about it.Does there have to be a reason? Tastes change over time.
Personally, I've gone the other direction, preferring low-magic settings, and even humans-only settings. But of late, i've found myself more interested in gonzo. I don't think there's any particular reason, except maybe to just scratch an itch that hasn't been scratched much.
I mean, spells like Tiny Hut, Goodberry, Teleport, et al. have been a part of D&D for a long time, and I've used them as DM and player in AD&D for a long time--happy to do so! But, for some reason, I feel spells like Teleport should be in tier 4, not tier 2. I feel like casters should get their proficiency bonus in spells per long rest. I feel like magic items should be super rare, and a simple +1 weapon a treasured heirloom.
Here's an example from 2005: my campaign (ran for about 5 years IRL) was winding up. The PCs had established a stronghold in some low mountains. Two of the creatures which lived there were Hill Giants the PCs had spared (from the Against the Giants series). Using their sweat (and other components/spells), the PCs crafted dozens and dozens of Potions of Hill Giant Strength. Enough to give one to every man, woman, and child in the castle complex (about 200 people IIRC). Oh, and every single guard had at least a +1 dagger or arrows, many had better weapons... Cast offs the PCs collected over the years.
Now, however, in 5E, I feel like this would be ridiculous.
