We played SCP with D20 Modern once...it was pretty interesting.
The concept of this universe where anomalies exist and the whole lore that's built up around it online are really interesting to me. I remember reading through the entries for like a half day on the website when I first discovered it and thinking it'd be the perfect lore codex for a tabletop campaign. I guess I wasn't the only person who thought that.
