but its a little intimidating haha.
Welcome to GURPS, there's a lot lol
Any recommendations for me to bring to a oneshot night to show why Gurps is neat?
That's hard to pinpoint for me, honestly. The thing that makes GURPS neat is how it can be used for any setting you can imagine, so it's difficult to try and encapsulate that in a single session IMO. I'd try to find out what the group prefers as far as setting goes and then choose based on that. If you're running it for strangers then just pick what setting you prefer.
This is a handy resource for a full listing of GURPS one-shot adventures. On that page you can see which setting each one shot is in for a general flavor of what you'd be running. Searching that site for articles tagged with GURPS will also get you some more results listed chronologically.
If you're REALLY intimidated or at least worried your players might be, you can always start with GURPS Lite too. Although, that's for 4th edition.
