This is just the kind of scenario that makes me want clean, concise, widely applicable rules that I can use to deal with whatever BS the players come up with. It wouldn't really help me if there were rules for athletic contests if they were in some obscure supplement, anyway.
I ran a Dragonbane mini-campaign this spring, and we enjoyed it. The rules are simple, and I found the lack of crunch made the players more willing to roleplay (rather than bring their characters to life via mechanics). Dragonbane is based on Chaosium's BRP system, which is my favorite.After sitting down and reading through the Dragonbane rulebook last night, I have realized that I just don't want to pour through 1000 pages of rules to run/play D&D anymore. Therer is no reason that 5E (or any other edition for that matter) can't be presented in a concise, complete, robust form like Dragonbane.
Do you like games in "long form" -- by that I mean the multiple rulebook, dense prose form common in the industry and exemplified by D&D and Pathfinder? Do you prefer a singular book but of the same form, like we usually get from Free League and Modiphius? Or do you like short and concise books?
I think Shadowdark is a nice compromise for me: the rulebook is 300 pages, but also A5 sized, and much of it is inspirational tables. The actual rules could easily fit in 100 pages.
I may revive a project I was working on during the pandemic: 5E in 100 pages. Not a deeply cut "basic" version in 100 pages, but an honest to goodness full version of 5E from the SRD in 100 pages.
About long campaigns. As far as I am concerned there's nothing preventing a long campaign for "smaller" sets of rules. And historically, we have several examples of this.
- Call of Cthulhu has Masks of Nyarlathotep, Horror on the Orient Express and Beyond the Mountains of Madness.
- Warhammer Fantasy Roleplay has The Enemy Within. Although I might be stretching the definition of "smaller" set of rules for WFRP.
Well we played Masks of Nyarlathotep using the second edition rules. No problems for us. On the train now so I don’t have it at hand to look up page count but I remember it to be around 100 pages or so.I felt you were stretching the definition of a smaller set of rules to count BRP/Cthulhu.
EDIT: Btw 200 pages of weapons for Call of Cthulhu? Two pages is plenty for that, IMO.
