What's that smell?
Ugh... another case of ridiculous comparisons:
Macs are better than PCs!
PCs are better than Macs!
Apples are better than oranges!
Oranges are better than apples!
Dodge Vipers are better than AMC Gremlins!
AMC Gremlins are... uhm... nevermind.
Anyway...
What are you comparing?
• Harnmaster vs. D&D-3E d20?
• Harnworld vs. Greyhawk? vs. Forgotten Realms?
• Harniacs vs. D&Ders?
There appears to be no objective way to compare any of these. Only personal experience and preferences.
To get an idea of where I'm coming from allow me to encapsulate my RPG resume: I started in OD&D back in `79 eventually moving to 1E. I evolved from plain kill-and-plunder to monte haul epics to plots of intrigue. I quit during 2E exploring countless games including Harn. After a few years of drifting, I quit RPGs entirely. Early last year I returned for 3E...
IMX:
As for
D&D, I like the easily adaptable nature of it. It's a little too simplistic at times, but it's a payoff for ease of use. As a DM, it is my responsibility to determine where and how these moments are resolved.
I generally use my own campaign worlds so
Greyhawk and
Forgotten Realms are unfamiliar territory beyond hearsay and a few adapted supplements/modules. They pretty much run the gamut in detail and style... but are for the most part well done.
The world of
Harn is a meticuouly detailed campaign with more stuff than anyone would ever need. But beyond detail, it is full of realistic dark-age flavour all the way down to
very inspiring Eric Hotz artwork (at least in the original version).
If you want a world with exquisite maps, tons of detail, set in a low population, low magic world... then this is the place for you. Otherwise steer clear.
Harnmaster is equally rich and detailed... but WAY too much bookwork for my tastes. With all the derived stats and skills, my first character took an hour to make.
Roleplayers have their own preferences and will always clash somewhere. I prefer more cinematic stories and D&D does that for me. HM is wonderfully real, but just too damn much bean-counting. Yes, I suppose as a few have said, you could declare that only the most intelligent would play with Harnmaster... you could also say HM is only for the most anal-retentive.
There's plenty that'll argue one's better than the other, but few that can bridge the gap and enjoy both.
Apples and oranges... Macs and PCs...
BTW: ColonelHardisson - Geeks calling geeks geeks.

Too rich.
