More of the gonzo Super Science & Sorcery variety so to this end I've combined C&C with Dungeon Crawl Classics. So I've ported over the DCC magic system into C&C to get the type of a game that my players have been looking for.
Not only has using these books been tremendously effective in bringing to life a complete campaign setting but its been highly influential in how I think about the OSR in general.
Not only does this approach solve many of my budget problems but it brings home the fact that DYI Dungeons & Dragons is the best Dungeons & Dragons. I've been using many resources from fifth edition as well & not giving two figs what others think. There are some incredible resources with in the OGL & I'm getting very tired of being completely hamstrung by innate attitudes of others when it comes to the table top rpg hobby. Especially when I see many OSR players & DM's showing off their latest purchases of these.
Only to be followed up with a score of one of Fifth edition's latest Dungeons & Dragons title Ghosts of Saltmarsh. Which could easily be ported back over into the OSR's Astonishing Swordsmen & Sorcerers of Hyperborea as a huge multi part Saltmarsh campaign from U1 all way through with AS&SH's own adventure The Mystery At Port Greely.
By combining these seemingly unrelated adventures the DM gets an epic 'Deep One' campaign that could take years to complete & could show the players the true scale of a massive legendary campaign of sanity shattering monstrousness. Editions & books should not hold back the creative spark hence why DYI Dungeons & Dragons is the best Dungeons & Dragons. Keep em rolling.
