I think that, in order to demo/view a ruleset in the unlicensed (free) version, you need to have a prepared campaign folder generated in a Full or Ultimate version. I don't think the demo will generate a campaign on its own.

For the MoreCore ruleset and its extension rulesets you can add a fair amount of game data to the PCs and you can export those even with a Demo version.
You can create and use any other data in that session only as you cannot save any other data.
The Free Client can also use Manage Characters to create/edit PCs in supported rulesets.
Ive added links in for a few more systems.
Fall of Delta Green
Shadowrun 5E
Shadow of the Demon Lord
Esoterrorists
Added Doctor Who
Can you add mine to the list as well?

Is anyone working on Exalted 3rd Edition, by any chance? Or Marvel Heroic Roleplaying (I've seen a character sheet for it)?
Any chance the Alien RPG can get its own forum room? The thread linked here goes to the thread where the guy writing the ruleset is doing his development work and hunting down bugs, it’s not really a place for us to share ideas and content.
FWIW, I think the game system is going places, and a dedicated space for us to chat about it and FG would help us build the community for it within FG much easier.
