Hero
With an hour's prep I can run many systems so I'd probably pick something to contrast with my current campaigns. Also something that shines as a one-shot rather than a campaign.Friends you haven't seen in a while ask you to run a TTRPG for them TONIGHT. You have nothing prepared, but access to your TTRPG collection/library/whatever. They are ambivalent about what game to play, and you think they will like whatever you run. So, what do you run?
Right now, I'd run HEROES OF THE HEARTH from Pelgrane Press's SEVEN WONDERS (Seven Wonders) because it's a fun-looking one shot I'd like to give a whirl.
If I think the people might prefer a more traditional feel, Call of Cthulhu is great for one-shots and the BRP system is both relatively crunchy and easy to explain a character sheet, so it's a great choice. I run a lot of FATE so if I want a more narrative feel, I'd go for that. But I might just look at something on my shelf and say "hey, Life With Master it is". So many simple, fun indie games ut there that work for one shots.
I guess that would be my answer. My go-to would be to pick an indie one-shot.
