Two is a group, and good for some relaxed play. If we can agree on a setting, I can whip up a short, simple mission. However, the problem with Savage Worlds is that it's not free, not even as an SRD. You either need the book itself, or I can make a character for a player without the book. The rules are easy to learn on the go, but chargen is tied to the core book.
Sprawlrunners: cyberpunk, with a fluid equipment system.
Accursed: after an invasion of witches, many people are transformed into scary creatures, including the characters.
The Thin Blue Line: Detroit Police Department, perfect for a pair of player detectives. Optional supernatural tones.
Rippers: Victorian monster hunters enhanced by abilities and special tools.
Sundered Skies: Steampunk flying ships in a post-apocalyptic world broken into parts.
Seven Worlds: Hard sci-fi with no alien species.
Ghost Ops: Operators (modern mercenaries) going on combat missions.
