I'll mostly be posting about table top RPGs, CGI, photography and writing but also probably whatever random thought crosses my mind Liverpool (the place not the FC) I do back end website development and accessibility for a living

I need to amend a previous statement I made here... The first film/TV that scared me was not the acid spider bots in Runaway it was the Goodies v Magic Roundabout from The Goodies Rule – O.K.?

I know its not the done thing since before I started playing but I thought I'd make two graphs to help players understand the odds of succeeding and bad things happening to their PCs in my current game Got out my scanner and scanned an actual pad of graph paper as the background
Graph showing change of success increases with number of traits used

Graph showing chance of avoiding bad things happening as Hazard Points decreases as Hazard Points increase

I've got a Code Names table in and I'm going to put in a note that a player can use one for their PC while they come up with a real name PC examples will have real names Here's the work in progress of character creation and example character for a straight setting with no fantasy elements
Example of character generation...

Last version gets rid of some of the stuff added based on a passport so gets more space Not sure if losing the flavour stuff is really a problem. It does leave some space for a couple of extra setting specific traits for PCs Before I carry on I'd be really interested if anyone has any comments
Character sheet laid out like a passport with each field labelled in English and French:
* Name
* Profession
* Nation and date of Birth
* Social Situation
* Skill
* Skill
* Esoteric knowledge
* Personal style 
* Weapon
* Tool
* Personal Item

And a space for a sketch of the character

Second version moves everything to one coloumn This doesn't give a lot of space in the main column if a variation on the game needs extra traits for characters It does open up the space on the right for a Hazard point track or something else

First version * includes some extra information that's on passports like height and hair colour * removes some of the powers related stuff as that's a work in progress rules I could easily make height and hair colour etc work in the rules since any character trait gives a bonus in play

Since the game I've been running seems to be creeping into being my pick up and play fill in for when other GMs need a break I thought I'd try making some improvements to the character sheet Taking inspiration from 1960s passports to play on the international agents theme

I seem to have gone down a bit of a rabbit hole of different ways to index and randomise a hexagonal grid of hexagons
11 different grids of 37 hexagons. Random d66 hex chooser. Numbered spiral from centre, Numbered Top to Bottom, Left to Right, Compass directions from centre, Clock numbering, Distance from centre, Numbering on each ring from centre, Strips, Edges, Scatter from a centre point (chosen using one of the other random methods) 1d6: 1-3=centre, 4-5= inner ring position 1d6 or 6 Outer ring position 1d12, Row lettering

Ongoing adventures in QGis. Made a spreadsheet of 169 locations in UK that might show up in a thriller. Geocoded each one. Loaded into QGis. Took the output as a PDF into Affinity 3. Split the text and pictorial elements. Ran some post processing on pictorial then reassembled.
