sandbox-system-builder VS worldbuilding

Foundry is great if there's a module and probably not worth the effort if there isn't. You can try putting together what you need from either https://gitlab.com/rolnl/sandbox-system-builder/-/tree/master or https://github.com/foundryvtt/worldbuilding both if which have some youtube tutorials.

Most systems are already made for you by the fantastic community and some of the game devs ( https://foundryvtt.com/packages/systems ). If the game system you choose to run isn't in foundry then there are tons of modules to modify how dice work, and even a few that allow you to create your own game system ( https://gitlab.com/rolnl/sandbox-system-builder/-/tree/master ). There's also an insane list of systems that aren't listed in Foundry's system that has been created, and can be found via discord or a google search. The community support for this VTT is beyond outstanding, and the discord is full of people answering the most obscure use case questions imaginable. It's rare for me to hear of a system/use case that can't be done here.

A few weeks ago I started making a generic WOiN system using the Sandbox System Builder (https://gitlab.com/rolnl/sandbox-system-builder) for FoundryVTT to support my party as Fantasy Grounds has been giving us issues.

Everything you need is on the Sandbox gitlab page

I'm probably going to be making a sandbox sheet for a game which foundry doesn't have yet so I've been looking into it a bit. If you're having trouble with sandbox, make sure your question isn't answered in the tutorial on the gitlab page. There are also youTube tutorials linked there, and a way to contact the creator of sandbox on discord to ask for help.

- Sandbox System Builder, which allows building of some fairly complex sheets without coding

Go through the readme on the official project page, which contains a step by step tutorial, and you'll have a simple system up in no time. Then get tricky with more advanced stuff. In two of the systems I built, I created character species where the character automatically inherited all the appropriate bonuses, skills,etc when they added that species to their character. https://gitlab.com/rolnl/sandbox-system-builder/-/tree/master

And then there's Simple Worldbuilding System, in case there's not a system already for the game OP wants to run. That one explicitly provides "A simple game system for Foundry VTT which allows for flexible definition of Actors and Items to assist with worldbuilding or for running games which do not have a more complete system implementation available."

Would the simplest option be to take the Simple World Building system and then try to slap on the 5e character sheet while modifying it as appropriate to Paranoia. Looks like the layout of the sheets are here and some of the code that drives them is here and here. Or would it be better to just duplicate the 5e repository and modify the sheets there?

For systems that haven't been developed for FoundryVTT, there is the Simple Worldbuilding System.

There is the Simple Worldbuilding System (https://gitlab.com/foundrynet/worldbuilding) and Sanbox System (https://gitlab.com/rolnl/sandbox-system-builder/-/tree/master) that let you create a basic system without coding, but they're pretty limited.
