I am quite interested in running a pure sandbox campaign at the moment - especially after buying Carcosa.
Obviously I will need a lot of random tables. So I will collect them in this post.
I recently found the very useful random-generator.com where people can create their own RPG content.
This website has a few as a starting point:
Random Fantasy Tables called "Tables for Fables"
More Random Random Tables
Random authentic US names
Random name generator
Random Star Wars name generator
Random Letter Sequence generator
Seventh Sanctum Random Character Tables (they offer a lot more as well)
Completely random Warhammer FRPG 2nd edition character creation, including background
Random Labyrinth Lord / Old School Character
Random Gamma World characters
Random Synnibarr NPCs (no stats, all background!)
Superfast 1 outstanding stat NPCs from my blog (needs dice)
Encounters and Plots
Detailed plot generator recommended!!
Basic Plots in literature (needs dice and some serious thought)
Random City Encounters
Random Daily Mail headlines generator (Daily Mail is a right wing UK tabloid)
WotC's Random Adventure Hook Generator
Crazy Random Plot generator (can produce multiple layers)
Random Science fiction adventures (needs dice) This is part of a whole series of articles including random tables.
You should also not forget that just opening a random article on wikipedia can provide more inspiration than you will ever need.
Also fun: Random Crossover generator (originally for fanfiction, but also great for adventures)
On the following site you will find a lot of very sophisticated tools, like random map generators (and much more).
Random cities for contemporary gonzo in my blog (needs dice)
Check out this post in my blog: Random adventures
Faction Connection Diagram (for 4 factions; needs dice) from Vornheim
Best Random Tables for Gaming has not only tables, but also links to sites with lists of tables
If you want to point to any helpful resources, please, leave a comment!
I will add them to the list.
