For those who like H. Beam Piper's Paratime series, Cepheus Universal by Zozer Games is a good buy. Paul makes provision for Time Travel to parallel time lines, which is perfect for the Paratime series. Move Pennsylvania State Police Corporal Calvin Morrison to an alternate Pennsylvania or have Verkan Vall of the Paratime Police pay a visit. Check out the Paratime stories online and get some ideas. Or for even more fun, have them cross timelines and find themselves on the Starship Warden of Metamorphosis Alpha, with a massive range of weapons and technology. Space: 1889 would also be a great place to have fun with totally surprised characters.
