Whisper:
I haven't looked at Dungeon Fantasy in any real depth yet.
Question: I have all the major 4E source books. Do you think that it's worth getting the set? I haven't run anything as a DM in 20 years, and the purchase seems geared to organizing a game. Just curious what your impression of the book is, sort of like asking a second opinion.
One thing first: There are two "Dungeon Fantasy" 'lines' when talking GURPS right now...
DF: The long series which goes Dungeon Fantasy 1 Adventures, Dungeon Fantasy 2 Exploits, Dungeon Fantasy 3 The Next Level, etc
DFRPG: The box set. This is DF... just
condensed. It reprints all the rules from Basic, Campaigns, Low-Tech, and DF that 'are needed' to run a tight 'old schoolish' fantasy heartbreaker game.
My hot take? It depends on what you prefer. A quick, easy setup game with condensed rules prepackaged for convenience? Then DFRP is probably right up your alley.
If you want more then you should either get into DF, or start with DFRP and add the bits of the DF line that most interest you, liken them to supplements. Most things will line up perfectly.
If you prefer diggin in and 'getting your hands dirty' with campaign building, you might just want to stick with Fantasy, Magic, Martial Arts, Low Tech, etc and do it all yourself.
Personally, while I kinda like what they've done with DFRP, I'd have to add a few pages of rules back in to get what I want out of it (Extra Effort in Combat, some advanced injury rules, most of Martial Arts, a few more points for social skills on each template,etc).
